# HEDTools - Python

> Python tools for validation, analysis, and transformation of HED (Hierarchical Event Descriptors) tagged datasets.

## Overview

HED (Hierarchical Event Descriptors) is a framework for systematically describing both laboratory and real-world events as well as other experimental metadata. HED tags are comma-separated path strings that provide a standardized vocabulary for annotating events and experimental conditions.

**Key Features:**

- Validate HED annotations against schema specifications
- Analyze and summarize HED-tagged datasets
- Transform and remodel event data
- Full HED support in BIDS (Brain Imaging Data Structure)
- HED support in NWB (Neurodata Without Borders) when used the [ndx-hed](https://github.com/hed-standard/ndx-hed) extension.
- Platform-independent and data-neutral
- Command-line tools and Python API

## Quick start

### Online tools (no installation required)

For simple validation or transformation tasks, use the online tools at [https://hedtools.org/hed](https://hedtools.org/hed) - no installation needed!

Browser-based validation (no data upload) is available at [https://www.hedtags.org/hed-javascript](https://www.hedtags.org/hed-javascript)

A development version of the online tools is available at: [https://hedtools.org/hed_dev](https://hedtools.org/hed_dev)

### Python installation

**Requirements:** Python 3.10 or higher

Install from PyPI:

```bash
pip install hedtools
```

Or install from GitHub (latest):

```bash
pip install git+https://github.com/hed-standard/hed-python/@main
```

### Basic usage

```python
from hed import HedString, load_schema_version


# Load the latest HED schema
schema = load_schema_version("8.4.0")

# Create and validate a HED string
hed_string = HedString("Sensory-event, Visual-presentation, (Onset, (Red, Square))", schema)
issues = hed_string.validate()

if issues:
    print(get_printable_issue_string(issues, title="Validation issues found"))
else:
    print("HED string is valid!")
```

### Command-line tools

HEDTools provides a unified command-line interface with git-like subcommands:

```bash
# Main command (new unified interface)
hedpy --help

# Validate a BIDS dataset
hedpy validate-bids /path/to/bids/dataset

# Extract sidecar template from BIDS dataset
hedpy extract-sidecar /path/to/dataset --suffix events

# Validate HED schemas
hedpy schema validate /path/to/schema.xml

# Convert schema between formats (XML, MEDIAWIKI, TSV, JSON)
hedpy schema convert /path/to/schema.xml

```

**Legacy commands** (deprecated, use `hedpy` instead):

```bash
validate_bids /path/to/dataset
hed_validate_schemas /path/to/schema.xml
run_remodel /path/to/data /path/to/config.json
```

For more examples, see the [user guide](https://www.hedtags.org/hed-python/user_guide.html).

### Jupyter notebook examples

**Note:** Example notebooks are available in the [GitHub repository](https://github.com/hed-standard/hed-python/tree/main/examples) only, not in the PyPI package.

The [`examples/`](examples/) directory contains Jupyter notebooks demonstrating common HED workflows with BIDS datasets:

- **validate_bids_dataset.ipynb** - Validate HED annotations in a BIDS dataset
- **summarize_events.ipynb** - Summarize event file contents and value counts
- **sidecar_to_spreadsheet.ipynb** - Convert JSON sidecars to spreadsheet format
- **merge_spreadsheet_into_sidecar.ipynb** - Merge spreadsheet annotations into JSON sidecars
- **extract_json_template.ipynb** - Generate JSON sidecar templates from event files
- **find_event_combinations.ipynb** - Find unique combinations of event values
- **validate_bids_dataset_with_libraries.ipynb** - Validate with HED library schemas

To use these notebooks:

```bash
# Clone the repository to get the examples
git clone https://github.com/hed-standard/hed-python.git
cd hed-python

# Install HEDTools with Jupyter support
pip install -e .[examples]

# Launch Jupyter
jupyter notebook examples/
```

See [`examples/README.md`](examples/README.md) for more details.

## Documentation

📖 **Full Documentation:** [https://www.hedtags.org/hed-python](https://www.hedtags.org/hed-python)

- [User guide](https://www.hedtags.org/hed-python/user_guide.html) - Usage instructions
- [API reference](https://www.hedtags.org/hed-python/api/index.html) - Detailed API documentation
- [HED specification](https://www.hedtags.org/hed-specification) - Full HED standard specification

### Building docs locally

```bash
# Install documentation dependencies
pip install -e .[docs]

# Build the documentation
cd docs
sphinx-build -b html . _build/html

# Or use the make command (if available)
make html

# View the built documentation
# Open docs/_build/html/index.html in your browser
```

### Formatting with Black

This project uses [Black](https://black.readthedocs.io/) for consistent code formatting.

```bash
# Check if code is properly formatted (without making changes)
black --check .

# Check and show what would change
black --check --diff .

# Format all Python code in the repository
black .

# Format specific files or directories
black hed/
black tests/
```

**Windows Users:** If you encounter "I/O operation on closed file" errors, use the `--workers 1` flag:

```bash
black --workers 1 --check .
black --workers 1 .
```

**Configuration:** Black settings are in `pyproject.toml` with a line length of 127 characters (matching our ruff configuration).

**Exclusions:** Black automatically excludes `.venv/`, `__pycache__/`, auto-generated files (`hed/_version.py`), and external repos (`spec_tests/hed-examples/`, `spec_tests/hed-specification/`).

**CI integration:** All code is automatically checked for Black formatting in GitHub Actions. Run `black .` before committing to ensure your code passes CI checks.

## Configuration

### Schema caching

By default, HED schemas are cached in `~/.hedtools/` (location varies by OS).

```python
# Change the cache directory
import hed
hed.schema.set_cache_directory('/custom/path/to/cache')
```

Starting with `hedtools 0.2.0`, local copies of recent schema versions are bundled within the package for offline access.
