Python HEDTools¶
Welcome to the Python HEDTools documentation! This package provides comprehensive tools for working with Hierarchical Event Descriptors (HED) - a standardized framework for annotating events and experimental metadata in neuroscience and beyond.
What is HED?¶
HED is a standardized vocabulary and annotation framework designed to systematically describe events experimental data, particularly neuroimaging and behavioral data. It’s integrated into major neuroimaging standards:
Key features¶
Validation: Verify HED annotations against official schemas
Analysis: Search, filter, and summarize HED-annotated data
BIDS integration: Full support for BIDS dataset validation and processing
NWB support: Read and write HED annotations in NWB files using ndx-hed
Multiple formats: Work with JSON sidecars, TSV files, Excel spreadsheets
