Introduction

+

What is DANDI?

+

DANDI is:

+
    +
  • An open data archive to submit neurophysiology data for electrophysiology, +optophysiology, and behavioral time-series, and images from immunostaining experiments.
    • +
  • A persistent, versioned, and growing collection of standardized datasets.
    • +
  • A place to house data to collaborate across research sites.
    • +
  • Supported by the BRAIN Initiative and the AWS Public dataset programs.
    • +
+

DANDI provides significant benefits:

+ +

Properties of DANDI

+

Data identifiers: The archive provides persistent identifiers for versioned datasets and assets, thus improving reproducibility of neurophysiology research.

+

Data storage: Cloud-based platform on AWS. Data are available from a public S3 bucket. Data from embargoed datasets are available from a private bucket to owners only.

+

Type of data The archive accepts cellular neurophysiology data including electrophysiology, optophysiology, and behavioral time-series, and images from immunostaining experiments and other associated data (e.g. participant information, MRI or other modalities).

+

Accepted Standards and Data File Formats: NWB (HDF5), BIDS (NIfTI, JSON, PNG, TIF, OME.TIF, OME.BTF, OME.ZARR) +(see Data Standards for more details)

+

Neurophysiology Informatics Challenges and DANDI Solutions

+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
ChallengesSolutions
Most raw data stays in laboratories.DANDI provides a public archive for dissemination of raw and derived data.
Non-standardized datasets lead to significant resource needs to understand and adapt code to these datasets.DANDI standardizes all data using NWB and BIDS standards.
The multitude of different hardware platforms and custom binary formats requires significant effort to consolidate into reusable datasets.The DANDI ecosystem provides tools for converting data from different instruments into NWB and BIDS.
There are many domain general places to house data (e.g. Open Science Framework, G-Node, Dropbox, Google drive), but it is difficult to find relevant scientific metadata.DANDI is focused on neurophysiology data and related metadata.
Datasets are growing larger, requiring compute services to be closer to data.DANDI provides Dandihub, a JupyterHub instance close to the data.
Neurotechnology is evolving and requires changes to metadata and data storage.DANDI works with community members to improve data standards and formats.
Consolidating and creating robust algorithms (e.g. spike sorting) requires varied data sources.DANDI provides access to many different datasets.

Using DANDI

+

DANDI allows you to work with stored neurophysiology data in multiple ways. You can search, view, and download files, +all without registering for a DANDI account. As a registered user, you can also create these collections of data +along with metadata and publish them to the DANDI platform.

+

Dandisets

+

DANDI stores cellular neurophysiology data in Dandisets.

+

A Dandiset is a collection of assets (files and their metadata) and metadata about the collection.

+
    +
  • A Dandiset is organized in a structured manner to help users and +software tools interact with it.
    • +
  • Each Dandiset has a unique persistent identifier that you can use to go directly +to the Dandiset (e.g. https://identifiers.org/DANDI:000004). +You can use this identifier to cite the Dandiset in your publications or provide +direct access to a Dandiset.
    • +
+

Quick Start

+

If you are new to DANDI, all you need is an Internet connection to use the DANDI Web application to view +and download files from a +public +Dandiset. +Registration is not required.

+

To view a specific public Dandiset and download one of its files:

+
    +
  1. +

    At the top of the DANDI Web application, click PUBLIC DANDISETS to see all Dandisets currently available in the + archive. You can sort them by name, identifier, or date of modification.

    +
    2. +
  2. +

    Search for a specific Dandiset by contributor name, modality, or species.

    +
    3. +
  3. +

    Click a Dandiset to open its landing page and view important information such as contact information, + description, license, access information and keywords, and simple statistics.

    +
    4. +
  4. +

    From the right side of the Dandiset landing page, click FILES to see a list of all folders and files for that + Dandiset. Click the download icon to download a + specific file. +Note: To download an entire Dandiset, you will need to follow the instructions in the + Download section to install and use the DANDI Python client tool.

    +
    5. +
+

Next steps

+

Although anyone on the Internet +can view and download public Dandisets, registered users can also create Dandisets, upload data, and publish +the Dandiset to generate a DOI for it. +See the sections that follow for more detailed information about the DANDI project, as well as instructions on how +to work with public Dandisets or to create and publish you own as a registered user.

+

Dandiset Actions

+

The DANDI project contains the DANDI Web application, the DANDI Python client tool, and the DANDI JupyterHub +instance. These tools can be used to perform actions on Dandisets.

+

+

You can learn more about the Dandiset actions in separate sections:

+ +

Tools to interact with DANDI

+

DANDI Web application

+

The DANDI Web application allows you to:

+
    +
  • Search across all public Dandisets
    • +
  • Download data from public Dandisets
    • +
  • Create a new Dandiset and provide metadata
    • +
  • Publish your Dandiset
    • +
+

DANDI Python client

+

The DANDI Python client allows you to:

+
    +
  • Download Dandisets and individual subject folders or files
    • +
  • Organize your data locally before upload
    • +
  • Upload Dandisets
    • +
+

Before you can use the DANDI Python client, you have to install the package with pip install dandi in a Python 3.8+ +environment.

+

You should check the Dandi Debugging section in case of any problems.

+

Dandihub analysis platform

+

Dandihub provides a JupyterHub instance in the cloud to interact with the data stored in DANDI.

+

To use the hub, you will need to register for an +account using the DANDI Web application. +Note that Dandihub is not intended for significant computation, but provides a place to introspect Dandisets and to perform some analysis and visualization of data.

+

Technical limitations

+
    +
  • File name/path: There is a limit of 512 characters for the full path length within a dandiset.
    • +
  • Volume and size: There is a limit of 5TB per file. We currently + accept any size of standardized datasets, as long as you can upload them over + an HTTPS connection. However, we ask you contact us if you plan to upload more than 10TB of data.
    • +
+

Citing DANDI

+

You can add the following statement to the methods section of your manuscript.

+
+

Data and associated metadata were uploaded to the DANDI archive [RRID:SCR_017571] using + the Python command line tool (https://doi.org/10.5281/zenodo.3692138). The data were first + converted into the NWB format (https://doi.org/10.1101/2021.03.13.435173) and organized + into a BIDS-like (https://doi.org/10.1038/sdata.2016.44) structure.

+
+

You can refer to DANDI using any of the following options:

Viewing Dandisets

+

Browse Dandisets

+

When you go to the DANDI Web application, you can click +on PUBLIC DANDISET to access all Dandisets currently available +in the archive, and you can sort them by name, identifier, size, or date of modification.

+

+

Search Dandisets

+

In addition, you can search across the Dandisets for any text part of the Dandiset metadata record. +The text may be about contributor names, modalities, or species. For example, "house mouse" will +return a subset of all Dandisets, while "mouse house" will likely not return any. When unquoted each +word is used as an OR.

+

+

When you click on one of the Dandisets, you can see that the searching phrase can +appear in the description, keywords, or in the assets summary.

+

+

Dandisets Metadata

+

The landing page of each Dandiset contains important information including +metadata provided by the owners such as contact information, description, license, access information and keywords, + simple statistics for a Dandiset such as size of the Dandiset and number of files, or + a summary of the Dandiset including information about species, techniques, and standards.

+

+

If you scroll down, you will also find: +- Assets Summary +- Funding Information +- Related Resources

+

While most of the metadata is summarized on the landing page, some additional information can be +found by clicking Metadata on the right-side panel. For Dandiset owners, this button also allows +adding relevant metadata to populate the landing page.

+

+

File View

+

The right side panel allows you also to access a file browser to navigate the list of folders and files +in a Dandiset.

+

+

Any file in the Dandiset has a download icon +You can click this icon to download a file to your device where you are browsing +or right click to get the download URL of the file. +In addition, there is an info icon that leads to full asset metadata. Some files also have a link to external +services that can open the file. Note: that these services often have size limits and hence are activated only for appropriately sized files.

Downloading Data and Dandisets

+

You can download the content of a Dandiset using the DANDI Web application (such a specific file) or entire +Dandisets using the DANDI Python CLI.

+

Using the DANDI Web Application

+

Once you have the Dandiset you are interested in (see more in the Dandiset View section), you can download the content of the Dandiset. +On the landing page of each Dandiset, you can find Download button on the right-hand panel. After clicking the +button, you will see the specific command you can use with DANDI Python CLI (as well as the information on how to download the CLI).

+

+

Download specific files

+

The right-side panel of the Dandiset landing page allows you also to access the list of folders and files.

+

+

Each file in the Dandiset has a download icon next to it, clicking the icon will start the download process.

+

Using the Python CLI Client

+

The DANDI Python client gives you more options, such as downloading entire +Dandisets.

+

Before You Begin: You need to have Python 3.8+ and install the DANDI Python Client using pip install dandi. +If you have an issue using the Python CLI, see the Dandi Debugging section.

+

Download a Dandiset

+

To download an entire Dandiset, you can use the same command as suggested by DANDI web application, e.g.:

+

dandi download DANDI:000023

+

Download data for a specific subject from a Dandiset

+

You can download data for specific subjects. +Names of the subjects can be found on DANDI web application or by running a command with the DANDI CLI: dandi ls -r +DANDI:000023. +Once you have the subject ID, you can download the data, e.g.:

+

dandi download https://api.dandiarchive.org/api/dandisets/000023/versions/_draft_/assets/?path=sub-811677083

+

You should replace _draft_ with a specific version you are interested in (e.g. 0.210914.1900 in the case of this Dandiset).

+

You can also use the link from DANDI web application, e.g.:

+

dandi download https://dandiarchive.org/dandiset/000023/0.210914.1900/files?location=sub-541516760%2F

+

Download a specific file from a Dandiset

+

You can download a specific file from a Dandiset when the link for the specific file can be found on the DANDI web +application, e.g.:

+

dandi download https://api.dandiarchive.org/api/dandisets/000023/versions/0.210914.1900/assets/1a93dc97-327d-4f9c-992d-c2149e7810ae/download/

+

Hint: dandi download supports a number of resource identifiers to point to a Dandiset, folder, or file. Providing +an incorrect URL (e.g. dandi download wrongurl) will provide a list of supported identifiers.

+

Using DataLad

+

All dandisets are regularly mirrored to DataLad datasets which are made available at the GitHub organization https://github.com/dandisets. +Where present, individual Zarr files are included as subdatasets (git submodules) hosted in the GitHub organization https://github.com/dandizarrs/.

+

The Git revision histories of each dataset reflect the Dandiset's draft state as of each execution of the mirroring job. +Published Dandiset versions are tagged with Git tags.

+

With DataLad, you can: +- clone an entire dataset, +- use a specific version of it, +- explore history of modifications, +- download content of files of interest, +- locally discard the content of no-longer-needed files, +- use the dataset in a reproducible manner, +- include it as a subdataset in your own DataLad dataset, +- use https://github.com/datalad/datalad-fuse/ to FUSE-mount individual locally-cloned dandisets so that their files' contents are transparently streamed to your DANDI/DataLad-unaware tools, +- etc.

+

Learn more about DataLad from its handbook at https://handbook.datalad.org/.

+

Developers' note: DataLad datasets are created using the dandi/backups2datalad tool which is also available for use by the community to similarly maintain mirrors of independent DANDI deployments as DataLad datasets.

+

Using WebDAV

+

DANDI provides a WebDAV service at https://webdav.dandiarchive.org/ for accessing the data in the DANDI archive. +You can use any WebDAV client or even a web browser to access the data - any dandiset, any version, any file or collection of files. +You can use any web download tool to download the data from the DANDI archive, e.g.

+
wget -r -np -nH --cut-dirs=3 https://webdav.dandiarchive.org/dandisets/000027/releases/0.210831.2033/
+
+

for a download of a specific release 0.210831.2033 of the 000027 dandiset.

+

Note: The WebDAV service does not directly serve any file contents; it instead relies on redirects to AWS S3 storage where the contents are stored. +You might need to configure your WebDAV client to follow redirects; e.g., for the davfs2 WebDAV client, set follow_redirect to 1 in /etc/davfs2/davfs2.conf.

+

Developers' note: The WebDAV service's code is available at https://github.com/dandi/dandidav/ and can also be used for independent DANDI deployments.

Validation Levels for NWB Files

+

To be accepted by DANDI, NWB files must conform to criteria that are enforced via three levels of validation:

+

NWB File Validation

+

PyNWB validation is used to validate the NWB files, +ensuring that they meet the specifications of core NWB and of any NWB extensions that were used. Generally +speaking, all files produced by PyNWB and MatNWB should pass validation, however there are occasional bugs. More +often, NWB files that fail to meet these criteria have been created outside PyNWB and MatNWB.

+

Critical NWB Checks

+

The NWB Inspector scans NWB files using heuristics to find mistakes +or areas for improvements in NWB files. There are three levels of importance for checks: CRITICAL, BEST PRACTICE +VIOLATIONS, and BEST PRACTICE SUGGESTIONS. CRITICAL warnings indicate some internal inconsistency in the data of the +NWB files. The NWB Inspector will print out all warnings, but only CRITICAL warnings will prevent a file from being +uploaded to DANDI. Errors in NWB Inspector will be block upload as well, but reflect a problem with the NWB +Inspector software as opposed to the NWB file.

+

Missing DANDI Metadata

+

DANDI has requirements for metadata beyond what is strictly required for NWB validation. The following metadata must +be present in the NWB file for a successful upload to DANDI: +- You must define a Subject object. +- The Subject object must have a subject_id attribute. +- The Subject object must have a species attribute. This can either be the Latin binomial, e.g. "Mus musculus", or + an NCBI taxonomic identifier. +- The Subject object must have a sex attribute. It must be "M", "F", "O" (other), or "U" (unknown). +- The Subject object must have either date_of_birth or age attribute. It must be in ISO 8601 format, e.g. "P70D" + for 70 days, or, if it is a range, must be "[lower]/[upper]", e.g. "P10W/P12W", which means "between 10 and 12 weeks"

+

These requirements are specified in the +DANDI configuration file of NWB Inspector.

+

Passing all of these levels of validation can sometimes be tricky. If you have any questions, please ask them via the +DANDI Help Desk and we would be happy to assist you.

Creating Dandisets and Uploading Data

+

This page provides instructions for creating a new Dandiset and uploading data to DANDI.

+

Prerequisites

+
    +
  1. +

    Convert data to NWB. You should start by converting your data to NWB format (2.1+). We suggest beginning the conversion process using only a small amount of data so that common issues may be spotted earlier in the process. + This step can be complex depending on your data. Consider using the following tools:

    +
      +
    1. NWB Graphical User Interface for Data Entry (GUIDE) is a cross-platform desktop application for converting data from common proprietary formats to NWB and uploading it to DANDI.
      2. +
    2. NeuroConv is a Python library that automates conversion to NWB from a variety of popular formats. See the Conversion Gallery for example conversion scripts.
      3. +
    3. PyNWB and MatNWB are APIs in Python and MATLAB that allow full flexibility in reading and writing data. (PyNWB tutorials, MatNWB tutorials)
      4. +
    4. NWB Overview Docs points to more tools helpful for working with NWB files.
      5. +
    +

    Feel free to reach out to us for help.

    +
    2. +
  2. +

    Choose a server.

    +
      +
    • Production server: https://dandiarchive.org. This is the main server for DANDI and should be used for sharing neuroscience data. + When you create a Dandiset, a permanent ID is automatically assigned to it. + This Dandiset can be fully public or embargoed according to NIH policy. + All data are uploaded as draft and can be adjusted before publishing on the production server.
      • +
    • Development server: https://gui-staging.dandiarchive.org. This server is for testing and learning how to use DANDI. + It is not recommended for sharing data, but is recommended for testing the DANDI CLI and GUI or as a testing platform for developers. + Note that the development server should not be used to stage your data.
      • +
    +

    The below instructions will alert you to where the commands for interacting with these two different servers differ slightly.

    +
    3. +
  3. +

    Register for DANDI and copy the API key. To create a new Dandiset and upload your data, you need to have a DANDI account.

    + +
    4. +
+

Data upload/management workflow

+

The NWB GUIDE provides a graphical interface for inspecting and validating NWB files, as well as for uploading data to +DANDI. See the NWB GUIDE Dataset Publication Tutorial for more information.

+

The below instructions show how to do the same thing programmatically using the command line interface (CLI). +The CLI approach may be more suitable for users who are comfortable with the command line or who need to automate the process, or for advanced use-cases.

+
    +
  1. Create a new Dandiset.
      +
    • Click NEW DANDISET in the Web application (top right corner) after logging in.
      • +
    • You will be asked to enter basic metadata: a name (title) and description (abstract) for your dataset.
      • +
    • After you provide a name and description, the dataset identifier will be created; we will call this <dataset_id>.
      • +
    +
    2. +
  2. +

    Check your files for NWB Best Practices. + Run NWB Inspector programmatically. Install the Python library (pip install -U nwbinspector) and run:

    +
    nwbinspector <source_folder> --config dandi
+
    +

    If the report is too large to efficiently navigate in your console, you can save a report using

    +
    nwbinspector <source_folder> --config dandi --report-file-path <report_location>.txt
+
    +

    For more details and other options, run:

    +
    nwbinspector --help
+
    +

    Thoroughly read the NWBInspector report and try to address as many issues as possible. + DANDI will prevent validation and upload of any issues labeled as level 'CRITICAL' or above when using the --config dandi option. + See "Validation Levels for NWB Files" for more information about validation criteria for + uploading NWB files and which are deemed critical. We recommend regularly running the inspector early in the process to generate the best NWB files possible. Note that some auto-detected violations, such as check_data_orientation, may be safely ignored in the event + that the data is confirmed to be in the correct form. See the NWBInspector CLI documentation for more information.

    +
    3. +
  3. +

    Install the DANDI Client.

    +
    pip install -U dandi
+
    +
    4. +
  4. +

    Validate NWB files. Perform a validation of the NWB files by running:

    +
    dandi validate --ignore DANDI.NO_DANDISET_FOUND <source_folder>
+
    +

    If you are having trouble with validation, make sure the conversions were run with the most recent version of dandi, PyNWB and MatNWB.

    +
    5. +
  5. +

    Upload the data to DANDI. This can either be done through the NWB GUIDE, or programmatically:

    +
    dandi download https://dandiarchive.org/dandiset/<dataset_id>/draft
+cd <dataset_id>
+dandi organize <source_folder> -f dry
+dandi organize <source_folder>
+dandi validate .
+dandi upload
+
    +

    Note that the organize steps should not be used if you are preparing a BIDS dataset with the NWB files. + Uploading to the development server is controlled via -i option, e.g. dandi upload -i dandi-staging. + Note that validation is also done during upload, but ensuring compliance using validate prior to upload helps avoid interruptions of the lengthier upload process due to validation failures. + If you have an issue using the DANDI Client, see the DANDI Debugging section.

    +
    6. +
  6. +

    Add metadata to the Dandiset. Visit your Dandiset landing page: + https://dandiarchive.org/dandiset/<dataset_id>/draft and click on the METADATA link.

    +
    7. +
+

Storing Access Credentials

+

There are two options for storing your DANDI access credentials.

+
    +
  1. +

    DANDI_API_KEY Environment Variable

    +
      +
    • +

      By default, the DANDI CLI looks for an API key in the DANDI_API_KEY + environment variable. To set this on Linux or macOS, run:

      +
      export DANDI_API_KEY=personal-key-value
+
      +
      • +
    • +

      Note that there are no spaces around the "=".

      +
      • +
    +
    2. +
  2. +

    keyring Library

    +
      +
    • +

      If the DANDI_API_KEY environment variable is not set, the CLI will look up the API + key using the keyring library, which + supports numerous backends, including the system keyring, an encrypted keyfile, + and a plaintext (unencrypted) keyfile.

      +
      • +
    • +

      Specifying the keyring backend

      +
        +
      • +

        You can set the backend the keyring library uses either by setting + the PYTHON_KEYRING_BACKEND environment variable or by filling in + the keyring library's configuration file.

        +
        • +
      • +

        IDs for the available backends can be listed by running keyring + --list.

        +
        • +
      • +

        If no backend is specified in this way, the library will use the + available backend with the highest priority.

        +
        • +
      • +

        If the DANDI CLI encounters an error while attempting to fetch the + API key from the default keyring backend, it will fall back to using + an encrypted keyfile (the keyrings.alt.file.EncryptedKeyring + backend). If the keyfile does not already exist, the CLI will ask + you for confirmation; if you answer "yes," the keyring + configuration file (if it does not already exist; see above) will be + configured to use EncryptedKeyring as the default backend. If you + answer "no," the CLI will exit with an error, and you must store the + API key somewhere accessible to the CLI on your own.

        +
          +
        • +

          Unless a different location is set via the keyring + configuration file, the encrypted keyfile will be located at the + following path:

          +
            +
          • +

            On Linux and macOS, if the XDG_DATA_HOME environment + variable is set to a nonempty string, the keyfile will be at + $XDG_DATA_HOME/python_keyring/crypted_pass.cfg; otherwise, + it will be at + ~/.local/share/python_keyring/crypted_pass.cfg.

            +
            • +
          • +

            On Windows, if the LOCALAPPDATA environment variable is + set, the keyfile will be at %LOCALAPPDATA%\Python + Keyring\crypted_pass.cfg; otherwise, if the ProgramData + environment variable is set, the keyfile will be at + %ProgramData%\Python Keyring\crypted_pass.cfg; otherwise, + it will be at Python Keyring\crypted_pass.cfg within the + current directory.

            +
            • +
          +
          • +
        +
        • +
      +
      • +
    • +

      Storing the API key with keyring

      +
        +
      1. +

        You can store your API key where the keyring library can find it by using + the keyring program: Run keyring set dandi-api-dandi key and enter the + API key when asked for the password for key in dandi-api-dandi.

        +
        2. +
      2. +

        If the API key isn't stored in either the DANDI_API_KEY environment variable + or in the keyring, the CLI will prompt you to enter the API key, and then it + will store it in the keyring. This may cause you to be prompted further; you + may be asked to enter a password to encrypt/decrypt the keyring, or you may be + asked by your operating system to confirm whether to give the DANDI CLI access to the + keyring.

        +

Publishing Dandisets

+

Once you create a Dandiset, DANDI will automatically create a draft version +of the Dandiset that can be changed as many times as needed by editing the +metadata or uploading new files.

+

When the draft version is ready, you can publish your Dandiset. This results +in an immutable snapshot of your Dandiset with its own unique version number +that others can cite. If you need to change the data or metadata, you can do +so by continuing to modify the draft version and publishing a new version +when you are ready.

+

Follow these steps to publish your Dandiset:

+
    +
  1. +

    Edit the Dandiset metadata, aiming to fix all Dandiset metadata validation + errors, and include any other useful information. For example, you may want + to edit the following fields:

    +
      +
    • People and funding contributors
      • +
    • Protocol information
      • +
    • Keywords
      • +
    • Related resources such as publications and code repositories
      • +
    +
    2. +
  2. +

    Fix all asset metadata errors by modifying the asset files to eliminate + the errors and re-uploading them.

    +
    3. +
  3. +

    When all the Dandiset metadata and asset metadata errors are fixed, and the Dandiset is made public if it was initially embargoed, the + Publish button (on the right panel of the Dandiset landing page) will + be enabled and turn green. Click the button to publish your Dandiset.

    +
    4. +
  4. +

    In the lower right section of the Dandiset landing page, you should see + the new, published version of your Dandiset listed. Click on that link + to view this version.

    +
    5. +
+

NOTE: Dandisets with Zarr assets currently cannot be published. We are +actively working on enabling this feature.

+
+ + + + + + + +

Debugging

+

If something goes wrong while using the Python CLI client, the +first place to check for more information so that you can file a quality bug +report is the logs. Every command records a copy of its logs in a logfile, the location of which is +reported to the user when the command finishes running. The location of the +logs varies by platform, e.g.:

+
    +
  • Linux: ~/.cache/dandi-cli/log or $XDG_CACHE_HOME/dandi-cli/log
    • +
  • macOS: ~/Library/Logs/dandi-cli
    • +
+

Logs are named with a combination of the time at which the dandi command +started running and the process ID of the command.

+

Recent versions of the client include all possible debugging information in the +logs, but if you're using an older version, only log messages that were printed +to the user when the command ran are recorded. As a result, in order to get +complete debugging information, you may have to rerun the problematic command, +this time increasing the logging level by passing -l DEBUG or --log-level +DEBUG on the command line. Note that this option goes between the main +dandi command and the name of the subcommand:

+
# Right:
+dandi -l DEBUG upload
+
+# Wrong:
+dandi upload -l DEBUG
+
+

In addition, many commands can be put into a developer-specific mode for +showing raw progress information instead of fancy progress bars. For the +delete, organize, upload, and validate commands, this can be done by +setting the DANDI_DEVEL environment variable and passing --devel-debug to +the command:

+
DANDI_DEVEL=1 dandi upload --devel-debug
+
+

For the download command, the equivalent is the -f debug/--format debug +option:

+
dandi download -f debug
+
+

More advanced users who are familiar with the Python +debugger can instruct the client to +automatically open the debugger if any errors occur by supplying the --pdb +option to the command. Like the -l/--log-level option, the --pdb option +must be placed between dandi and the name of the subcommand.

+ + + + + + + + + + + + + +
+
+ + + +
+ +
+ + + +
+

Project Structure

+

The DANDI project can be represented schematically:

+

+

The Client side contains the DANDI Python CLI and DANDI Web application.

+

The Server side contains a RESTful API and DANDI JupyterHub.

+

The Dandiset is a file organization to store data together with metadata.

+

The DANDI project is organized around several GitHub repositories:

+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +

Data Standards

+

DANDI requires uploaded data to adhere to community data standards. +These standards help data curators package all the necessary metadata and provide a uniform structure so that data can be more easily understood and reused by future users. +DANDI also leverages these standards to provide features like data validation and automatic metadata extraction and search. +DANDI currently supports two data standards:

+ +

For microscopy data from immunostaining, we are using the BIDS extension for microscopy.

+

To share data on DANDI, you will first need to convert your data to an appropriate standard. +If you would like help determining which standard is most appropriate for your data, do not hesitate to reach out using the dandi helpdesk and we would be happy to assist.

+

Neurodata Without Borders (NWB)

+

NWB is a data standard for neurophysiology, providing neuroscientists with a common standard to share, archive, use, and build analysis tools for neurophysiology data. +NWB is designed to store a variety of neurophysiology data, including data from intracellular and extracellular electrophysiology experiments, data from optical physiology experiments, and tracking and stimulus data. +The NWB team supports APIs in Python (PyNWB) and MATLAB (MatNWB), with tutorials for writing data broken down by experiment type. +See the NWB Tutorials page for more details. +Also see the NWB Conversion Tools user guide for converting data for automated conversions from several popular proprietary data formats. +The best way to get help from the NWB community is through the NWB user Slack channel.

+

Brain Imaging Data Format (BIDS)

+

BIDS is a way to organize and describe neuroimaging and behavioral data. +See the Getting Started page for instructions for how to convert your neuroimaging data to BIDS.

+

For microscopy and associated MR data, use the BIDS extension for microscopy.

Data Licenses

+

To create a Dandiset, you must select a license under which to share the data. +Because the DANDI Archive provides a platform for open data sharing, the +licenses come from Creative Commons, an +international nonprofit organization dedicated to establishing, growing, and +maintaining a shared commons in the spirit of open source.

+

These licenses enable the dataset's copyright holder to grant permissions to +others to share and use the data for a wide range of purposes. The licenses +available to users of the Archive are as follows:

+
    +
  • +

    Attribution (CC-BY-4.0). +This license grants permission to share the data to others and to adapt the data +by remixing, transforming, and building upon it, so long as appropriate credit +is given to the copyright holder and any changes to the original are clearly +indicated. The dataset may be used for any purpose (even commercial ones). Note +that this license retains the original copyright while granting permissive +access to the data to all others.

    +
    • +
  • +

    Public domain dedication +(CC0-1.0). This license +dedicates the dataset to the public domain, relinquishing copyright and +therefore allowing anyone to use the dataset for any purpose without +restriction.

    +
    • +
+

You can learn more about the theory of how the Creative Commons licenses operate +at their website. If you have any +questions or concerns, send a message to help@dandiarchive.org.

Developer Notes

+

This page contains important information for anyone starting development work on the DANDI +project.

+

Overview

+

The DANDI archive dev environment comprises three major pieces of software: +dandi-archive, dandi-cli, and dandi-schema.

+

dandi-archive

+

dandi-archive is the web frontend +application; it connects to dandi-api and provides a user interface to all the DANDI functionality. +dandi-archive is a standard web application built with +yarn. See the dandi-archive README +for instructions on how to build it locally.

+

The Django application makes use of several services +to provide essential function for the DANDI REST API, including Postgres (to hold +administrative data about the web application itself), Celery (to run +asynchronous compute tasks as needed to implement API semantics), and RabbitMQ +(to act as a message broker between Celery and the rest of the application).

+

The easiest way to run the API along with its services is through a Docker +Compose setup, as detailed in the Develop with Docker quickstart.

+

dandi-cli

+

dandi-cli is a Python command line tool +used to manage downloading and uploading of data with the archive. You may need +to use this tool when developing new features for the frontend and +backend, but there are other methods of faking data in the system to work with +as well. You can install dandi-cli with a command like pip install dandi +(then invoke dandi on the command line to run the tool), or build it locally +following the instructions in the dandi-cli README.

+

dandi-schema

+

dandi-schema is a Python library for +creating, maintaining, and validating the DANDI metadata models for dandisets +and assets. You may need to make use of this tool when improving models, or +migrating metadata. You can install dandi-schema with a command like +pip install dandi-schema. When releases are published through dandi-schema, +corresponding json-schemas are generated in the release folder of the dandi schema repo. See the dandi-schema README for instructions on +viewing the schemas.

+

Technologies Used

+

This section details some foundational technologies used in dandi-archive. Some basic understanding of these technologies is the bare minimum +requirement for contributing meaningfully, but keep in mind that the DANDI team +can help you get spun up as well.

+

JavaScript/TypeScript. The DANDI archive code is a standard JavaScript web +application, but we try to implement new functionality using TypeScript.

+

Vue/VueX. The application's components are written in Vue, and global +application state is managed through VueX.

+

Vuetify. The components make heavy use of the Vuetify component library.

+

Python3. The backend code is written in Python 3.

+

Django/drf/drf-yasg. The API infrastructure is implemented through a Django application. +This means that application resources must be mapped to Django models, while +Django views mediate API responses. The REST endpoints are implemented via +Django Rest Framework (DRF), while DRF-YASG is used to generate Swagger +documentation.

+

For general help with dandi-archive, contact @waxlamp.

+

Deployment

+

The DANDI project uses automated services to continuously deploy both the +dandi-api backend and the dandi-archive frontend.

+

Heroku manages backend deployment automatically from the master branch of the +dandi-api repository. For this reason it is important that pull requests pass +all CI tests before they are merged. Heroku configuration is in turn managed by +Terraform code stored in the dandi-infrastructure repository. If you need +access to the Heroku DANDI organization, talk to @satra.

+

Netlify manages the frontend deployment process. Similarly to dandi-api, these +deployments are based on the master branch of dandi-archive. The +netlify.toml file +controls Netlify settings. The @dandibot GitHub account is the "owner" of the +Netlify account used for this purpose; in order to get access to that account, +speak to @satra.

+

Monitoring

+

Service(s) status

+

The DANDI project uses upptime to monitor the status of DANDI provided and third-party services. +The configuration is available in .upptimerc.yml of the https://github.com/dandi/upptime repository, which is automatically updated by the upptime project pipelines. +Upptime automatically opens new issues if any service becomes unresponsive, and closes issues whenever service comes back online. +https://www.dandiarchive.org/upptime/ is the public dashboard for the status of DANDI services.

+

Logging

+

Sentry

+

Sentry is used for error tracking main deployment. +To access Sentry, login to https://dandiarchive.sentry.io .

+

Heroku & Papertrail

+

The dandi-api and dandi-api-staging apps have the Papertrail add-on configured to capture logs. +To access Papertrail, log in to the Heroku dashboard, proceed to the corresponding app and click on the "Papertrail" add-on.

+

A cronjob on the drogon server backs up Papertrail logs as .csv files hourly at /mnt/backup/dandi/papertrail-logs/{app}. +Moreover, heroku logs processes per app dump logs to /mnt/backup/dandi/heroku-logs/{app} directory.

+

Continuous Integration (CI) Jobs

+

The DANDI project uses GitHub Actions for continuous integration. +Logs for many of the repositories are archived on drogon server at /mnt/backup/dandi/tinuous-logs/.

+

Code Hosting

+

All code repositories are hosted on GitHub. The easiest way to contribute is to +gain push access to the repositories by talking to @waxlamp; this way, you can +create pull requests based on branches within the origin repositories, which in +turn allows for Netlify deploy previews and Heroku staging previews to be built.

+

However, this is not strictly required. You can contribute using the standard +fork-and-pull-request model, but under this workflow we will lose the benefit of +those previews.

+

Email Lists

+

The project's email domain name services are managed via Terraform as AWS Route +53 entries. This allows the API server to send emails to users, etc. It also +means we need a way to forward incoming emails to the proper mailing list--this +is accomplished with a service called ImprovMX.

+

The email addresses info@dandiarchive.org and help@dandiarchive.org are +advertised to users as general email addresses to use to ask for information or +help; both of them are forwarded to dandi@mit.edu, a mailing list containing the +leaders and developers of the project. The forwarding is done by the ImprovMX +service, and more such email addresses can be created as needed within that +service.

+

If you need the credentials for logging into ImprovMX, speak to Roni +Choudhury (roni.choudhury@kitware.com).

+

Miscellaneous Tips and Information

+

Use email address to log into dev Django admin panel

+

Once dandi-api is up and running, you can access the Django admin panel at +http://localhost:8000/admin. The login page asks for a "username" but really it +is expecting the email address associated with the username.

+

One easy trick here is to supply the username again as the email address when +you are setting up the superuser during initial setup.

+

Refresh GitHub login to log into prod Django admin panel

+

To log into the production Django admin panel, you must simply be logged into +the DANDI Archive production instance using an admin account.

+

However, at times the Django admin panel login seems to expire while the login +to DANDI Archive proper is still live. In this case, simply log out of DANDI, +log back in, and then go to the Django admin panel URL +(e.g. https://api.dandiarchive.org/admin) and you should be logged back in +there.

+

Why do incoming emails to dandiarchive.org look crazy?

+

When a user emails help@dandiarchive.org or info@dandiarchive.org, those +messages are forwarded to dandi@mit.edu (see above) so that the +dev team sees them. However, these emails arrive with a long, spammy-looking +From address with a Heroku DNS domain; this seems to be an artifact of how +mit.edu processes emails, and does not occur in general (e.g. messages sent +from the API server to users).

Using the DANDI Hub

+

DANDI Hub is a JupyterHub instance in the cloud to interact with the data stored in DANDI, and is free to use for exploratory analysis of data on DANDI. +For instructions on how to navigate JupyterHub see this YouTube tutorial. +Note that DANDI Hub is not intended for significant computation, but provides a place to introspect Dandisets and to perform some analysis and visualization of data.

+

Registration

+

To use the DANDI Hub, you must first register for an account using the DANDI website. +See the Create a DANDI Account page.

+

Choosing a server option

+

When you start up the DANDI Hub, you will be asked to select across a number of server options. +For basic exploration, Tiny or Base would most likely be appropriate. +The DANDI Hub also currently offers Medium and Large options, which have more available memory and compute power. +The "T4 GPU inference" server comes with an associated T4 GPU, and is intended to be used for applications that require GPU for inference. +We request that users of this server be considerate of their usage of the DANDI Hub as a free community resource. +Training large deep neural networks is not appropriate. +A "Base (MATLAB)" server is also available, which provides a MATLAB cloud installation but you would be required to provide your own license.

+

Custom server image

+

If you need additional software installed in the image, you can add a server image that will be made available for all users in the Server Options menu. Add a server image by updating the profileList in the JupyterHub config file and submitting a pull request to the dandi-hub repository. Once the pull request is merged, the DANDI team will redeploy JupyterHub and the image will be available.

+

Example notebooks

+

The best way to share analyses on DANDI data is through the DANDI example notebooks. +These notebooks are maintained in the dandi/example-notebooks repository which provides more information about their organization. +Dandiset contributors are encouraged to use these notebooks to demonstrate how to read, analyze, and visualize the data, and how to produce figures from associated scientific publications.

+

Notebooks can be added and updated through a pull request to the dandi/example-notebooks repository. +Once the pull request is merged, your contributed notebook will be available to all DANDI Hub users.

    Revocation: Content not considered to fall under the scope of the repository + can be removed and associated DOIs issued by DANDI revoked. Inform the DANDI team + promptly, ideally no later than 24 hours from upload, about any suspected policy + violation. Alternatively, content found to already have an external DOI will + have the DANDI DOI invalidated and the record updated to indicate the original + external DOI. User access may be revoked on violation of Terms of Use.

    +
    • +
  • +

    Withdrawal: If the uploaded research object must later be withdrawn, the + reason for the withdrawal will be indicated on a tombstone page, which will + henceforth be served in its place. Withdrawal is considered an exceptional + action, which normally should be requested and fully justified by the original + uploader. In any other circumstance reasonable attempts will be made to contact + the original uploader to obtain consent. The DOI and the URL of the original + object are retained.

    +
    • +

    User data on Dandihub: At present, user data on Dandihub is being removed + periodically and Dandihub storage space should not be considered persistent.

+

Longevity

+
    +
  • Versions: Datasets are versioned when published. Prior to publishing the + state of a dataset may continue to evolve and the data or metadata are neither + versioned, nor guaranteed to persist. Derivatives of data files may be generated, but original content is + never modified.
    • +
  • Replicas: All data files are stored on an AWS public bucket, with replicas + housed at Dartmouth College. Data files are kept in multiple replicas at the + moment, but this may change over time, and no recovery mechanisms for unversioned data + should be assumed to be in place.
    • +
  • Retention period: Versioned items will be retained for the lifetime of the repository. + This is currently the lifetime of the NIH award, which currently expires in + April 2029.
    • +
  • Functional preservation: DANDI makes no promises of usability and + understandability of deposited objects.
    • +
  • File preservation: Data files and metadata are backed up nightly and + replicated into multiple copies in different storage services.
    • +
  • Fixity and authenticity: All data files are stored along with multiple + checksums of the file content. Files are regularly checked against their + checksums to assure that file content remains constant.
    • +
  • Succession plans: In case of a repository shutdown, our best efforts will + be made to integrate all content into suitable alternative institutional and/or + other repositories overlapping in the scope of the DANDI archive.

Terms of Use v1.0.1

+

The DANDI data archive ("DANDI") is offered by the DANDI project as part of its +mission to make available the results of its work.

+

Use of DANDI, both the uploading and downloading of data, denotes agreement with +the following terms:

+
    +
  1. +

    DANDI is an open dissemination research data repository for the preservation + and making available of research, educational and informational content. Access + to DANDI’s content is open to all.

    +
    2. +
  2. +

    Content may be uploaded free of charge by the US BRAIN Initiative and other + projects required to submit data to a public archive and those without ready + access to an organized data center.

    +
    3. +
  3. +

    The uploader is exclusively responsible for the content that they upload to + DANDI and shall indemnify and hold the DANDI team free and harmless in + connection with their use of the service. The uploader shall ensure that their + content is suitable for open dissemination, and that it complies with these + terms and applicable laws, including, but not limited to, privacy, data + protection and intellectual property rights [1]. In addition, where data that + was originally sensitive personal data is being uploaded for open dissemination + through DANDI, the uploader shall ensure that such data is either anonymized + to an appropriate degree or fully consent cleared [2].

    +
    4. +
  4. +

    Access to DANDI, and all content, is provided on an "as-is" basis. Users of + content ("Users") shall respect applicable license conditions. Download and + use of content from DANDI does not transfer any intellectual property rights + in the content to the User.

    +
    5. +
  5. +

    Users are exclusively responsible for their use of content, and shall indemnify + and hold the DANDI team free and harmless in connection with their download + and/or use. Hosting and making content available through DANDI does not + represent any approval or endorsement of such content by the DANDI team.

    +
    6. +
  6. +

    The DANDI team reserves the right, without notice, at its sole discretion and + without liability, (i) to alter, delete or block access to content that it + deems to be inappropriate or insufficiently protected, and (ii) to restrict + or remove User access where it considers that use of DANDI interferes with + its operations or violates these Terms of Use or applicable laws.

    +
    7. +
  7. +

    Unless specified otherwise, DANDI metadata may be freely reused under the + CC0 waiver.

    +
    8. +
  8. +

    These Terms of Use are subject to change by the DANDI team at any time and + without notice, other than through posting the updated Terms of Use on the + DANDI website.

    +
    9. +
  9. +

    Uploaders considering DANDI for the storage of unanonymized or encrypted/unencrypted + sensitive personal data are advised to use bespoke platforms rather than open + dissemination services like DANDI for sharing their data.

    +
    10. +
+

[1] [2] See further the user pages regarding uploading for information on anonymization +of datasets that contain sensitive personal information.

+

If you have any questions or comments with respect to DANDI, or if you are unsure +whether your intended use is in line with these Terms of Use, or if you seek +permission for a use that does not fall within these Terms of Use, please contact +us.

+

This Terms of Service document is derived from the Zenodo terms of service v1.2.

It\n * might be for example a function that you passed to Observable's constructor, but most of the time it is\n * a library implementation, which defines what will be emitted by an Observable, and when it be will emitted. This means\n * that calling `subscribe` is actually the moment when Observable starts its work, not when it is created, as it is often\n * the thought.\n *\n * Apart from starting the execution of an Observable, this method allows you to listen for values\n * that an Observable emits, as well as for when it completes or errors. You can achieve this in two\n * of the following ways.\n *\n * The first way is creating an object that implements {@link Observer} interface. It should have methods\n * defined by that interface, but note that it should be just a regular JavaScript object, which you can create\n * yourself in any way you want (ES6 class, classic function constructor, object literal etc.). In particular, do\n * not attempt to use any RxJS implementation details to create Observers - you don't need them. Remember also\n * that your object does not have to implement all methods. If you find yourself creating a method that doesn't\n * do anything, you can simply omit it. Note however, if the `error` method is not provided and an error happens,\n * it will be thrown asynchronously. Errors thrown asynchronously cannot be caught using `try`/`catch`. Instead,\n * use the {@link onUnhandledError} configuration option or use a runtime handler (like `window.onerror` or\n * `process.on('error)`) to be notified of unhandled errors. Because of this, it's recommended that you provide\n * an `error` method to avoid missing thrown errors.\n *\n * The second way is to give up on Observer object altogether and simply provide callback functions in place of its methods.\n * This means you can provide three functions as arguments to `subscribe`, where the first function is equivalent\n * of a `next` method, the second of an `error` method and the third of a `complete` method. Just as in case of an Observer,\n * if you do not need to listen for something, you can omit a function by passing `undefined` or `null`,\n * since `subscribe` recognizes these functions by where they were placed in function call. When it comes\n * to the `error` function, as with an Observer, if not provided, errors emitted by an Observable will be thrown asynchronously.\n *\n * You can, however, subscribe with no parameters at all. This may be the case where you're not interested in terminal events\n * and you also handled emissions internally by using operators (e.g. using `tap`).\n *\n * Whichever style of calling `subscribe` you use, in both cases it returns a Subscription object.\n * This object allows you to call `unsubscribe` on it, which in turn will stop the work that an Observable does and will clean\n * up all resources that an Observable used. Note that cancelling a subscription will not call `complete` callback\n * provided to `subscribe` function, which is reserved for a regular completion signal that comes from an Observable.\n *\n * Remember that callbacks provided to `subscribe` are not guaranteed to be called asynchronously.\n * It is an Observable itself that decides when these functions will be called. For example {@link of}\n * by default emits all its values synchronously. Always check documentation for how given Observable\n * will behave when subscribed and if its default behavior can be modified with a `scheduler`.\n *\n * #### Examples\n *\n * Subscribe with an {@link guide/observer Observer}\n *\n * ```ts\n * import { of } from 'rxjs';\n *\n * const sumObserver = {\n * sum: 0,\n * next(value) {\n * console.log('Adding: ' + value);\n * this.sum = this.sum + value;\n * },\n * error() {\n * // We actually could just remove this method,\n * // since we do not really care about errors right now.\n * },\n * complete() {\n * console.log('Sum equals: ' + this.sum);\n * }\n * };\n *\n * of(1, 2, 3) // Synchronously emits 1, 2, 3 and then completes.\n * .subscribe(sumObserver);\n *\n * // Logs:\n * // 'Adding: 1'\n * // 'Adding: 2'\n * // 'Adding: 3'\n * // 'Sum equals: 6'\n * ```\n *\n * Subscribe with functions ({@link deprecations/subscribe-arguments deprecated})\n *\n * ```ts\n * import { of } from 'rxjs'\n *\n * let sum = 0;\n *\n * of(1, 2, 3).subscribe(\n * value => {\n * console.log('Adding: ' + value);\n * sum = sum + value;\n * },\n * undefined,\n * () => console.log('Sum equals: ' + sum)\n * );\n *\n * // Logs:\n * // 'Adding: 1'\n * // 'Adding: 2'\n * // 'Adding: 3'\n * // 'Sum equals: 6'\n * ```\n *\n * Cancel a subscription\n *\n * ```ts\n * import { interval } from 'rxjs';\n *\n * const subscription = interval(1000).subscribe({\n * next(num) {\n * console.log(num)\n * },\n * complete() {\n * // Will not be called, even when cancelling subscription.\n * console.log('completed!');\n * }\n * });\n *\n * setTimeout(() => {\n * subscription.unsubscribe();\n * console.log('unsubscribed!');\n * }, 2500);\n *\n * // Logs:\n * // 0 after 1s\n * // 1 after 2s\n * // 'unsubscribed!' after 2.5s\n * ```\n *\n * @param {Observer|Function} observerOrNext (optional) Either an observer with methods to be called,\n * or the first of three possible handlers, which is the handler for each value emitted from the subscribed\n * Observable.\n * @param {Function} error (optional) A handler for a terminal event resulting from an error.
