Requirements

Python

Python 3.10 or newer.

Linux, macOS and Windows are all supported. The package is pure Python and depends on the standard scientific stack.

edf2asc (only for EyeLink data)

EyeLink EDF files are parsed by first converting them to ASCII with edf2asc, a tool from SR Research distributed inside the EyeLink Developers Kit.

1. Create a free account and download the kit from the SR Research support forum.
2. Install the kit (the installer places edf2asc in a system location on macOS/Windows and provides a .deb for Debian/Ubuntu Linux).
3. Make sure edf2asc is on your PATH. Verify with:

edf2asc -h

If you see a usage message, you're set. If not, add the install directory to PATH (or symlink the binary into /usr/local/bin).

You only need edf2asc when dataset_format="eyelink". Tobii, Gazepoint and WebGazer pipelines don't require it.

Python dependencies

Pyxations relies on the standard scientific Python stack:

• numpy, pandas, pyarrow, polars
• scipy, statsmodels
• matplotlib, seaborn, opencv-python
• remodnav, multimatch-gaze (eye-movement algorithms)
• tqdm

The pinned full list lives in pyproject.toml. pip install pyxations pulls them all in.
