HED (Hierarchical Event Descriptors) is a framework for systematically describing both laboratory and real-world events. HED tags are comma-separated path strings.
The goal of HED is to describe precisely the nature of the events of interest occurring in an experiment using a common language. HED, itself, is platform-independent and data-neutral.
Most people will simply annotate their events by creating a spreadsheet that associates HED tags with event codes or the events themselves. If you have such a spreadsheet, you can use the HED Online Validator currently available at https://hedtools.ucsd.edu/hed to validate or transform your files without downloading any tools.
- hedtools contains all of the validation and translation tools for HED tags and HED schema.
- webtools contains the code to deploy the validators and other HED tools as a web application running in a docker module.
The HEDTools require python 3.7 or greater.
Note: As of January 1, 2022, the hed-python repository will no longer support HED-2G.
The existing support continues to be available in the hed2-python repository. On online
version of the tools in this repository are available at
