DRS and 'DRS-like' clients

DRSClient.py

Superclass for DRS Clients

Gen3DRSClient.py

This is a python wrapper for the two DRS functions. It also handles Gen3 authentication using Fence. This is necessary until RAS/Passport support is in place.

There are two clients for specific Gen3 DRS servers

• crdcDRSClient - client for Cancer Research Data Commons DRS server
• bdcDRSClient - client for BioDataCatalyst DRS server

SBDRSClient.py

A DRS client for Seven Bridges DRS services. Handles SB specific authentication. Two specific classes are provided.

• sbcgcDRSClient - client for Seven Bridges Cancer Genomics Cloud DRS server
• cavaticaDRSClient - client for Cavatica DRS Server

sdlDRSClient.py

A DRS-like wrapper around the SRA Data Locator. Uses standard dbGaP/SRA authentication (.ngc file)

WES clients

DNAStackWESClient.py

Wrapper to make a WES call. Currently does an MD5 checksum and the plenary GWAS workflow. The plan is to use samtools and eventually a GWAS workflow.

sb_wes_client.py

Client to call Seven Bridges WES Servers. The specific features addressed include authentication, setting a project to work within and the use of apps stored in the Seven Bridges environment. For testing and demo purposes this client encapsulates running samtools.

elixir_wes_client.py

Client to call Elixir WES Servers. The specific features addressed include authentication, setting a project to work within and the use of apps stored in the Seven Bridges environment. For testing and demo purposes this client encapsulates running samtools.

WESClient.py

Superclass for WES clients. Has generic capability to run WES requiring full configuration of the request body and possibly knowledge of the specific WES server being called.

Other Workflow clients

These provide a WES like binding to proprietary APIs so that capabilities can be explored where no WES implentation so far exists.

GCPLSsamtools.py

Wrapper to prepare a job to run samtools as a GCP Life Sciences pipeline.

Requires: Google Life Sciences API installed and configured for your GCP account

SBsamtools.py

Submits a samtools stats task via Seven Bridges API. By preference should now use the SB WES Client

Requires: Seven Bridges API Python client installed and configured for your GCP account
