This repository contains user supporting code and documentation for using the Hierarchical Event Descriptor (HED) system for annotating, summarizing, and analyzing data. The repository is organized into three subdirectories:

The datasets subdirectory contains datasets for testing various aspects of HED. These datasets have stubs for actual imaging data in order to reduce their size. Most of these datasets have complete versions available on openNeuro. See datasets/README.md for details.

The src subdirectory contains Python Jupyter notebooks demonstrating calls to HedTools. For MATLAB support for HED see the hed-matlab GitHub repository.

The docs subdirectory contains the source documentation for this and other HED resources. The HED GitHub organization gathers the HED supporting resources, all of which are open source.
