A lightweight library to import SR Research EDF files into Python.

This Software is currenly pre-alpha, meaning it is currently being developed and is not ready for outside use

The Eyelink Data Format (EDF; not to be confused with the European Data Format ) is used for storing eyetracking data from Eyelink eyetrackers. It was put forward by the company SR Research. SR Research EDF files store data in a binary format, and reading these files currently requires the edfapi C library that is included in the Eyelink developers kit.

Strictly speaking, pyEyelink only requires Numpy, and that the user has the Eyelink developers kit installed on their maching (One must create a login on the forum to access the download). We also plan to create helper functions for converting data to pandas DataFrames or MNE-Python Raw instances, after reading the data in. These functions would require the user to have those packages installed.

This package was originally adapted from the pyeparse package (created by several of the core developers of MNE-Python). It copies much of the EDF (Eyelink Data Format) reading code.
