Eye-tracking resources (or: How I learned to stop worrying and love the Eye-Tracker)

This repo will help to understand how to set your experiment with the Eye-Tracker (for the moment Eye-Link 1000) and analyze the output in a thoughtful way. Its main goal is to gather together information/guides/links/codes/etc. .

TO DO

• extracting the function used by fieldtrip to convert the ascii output from the eyelink into a tsv file.

Output conversion

edf to ASCI

• edf2asc.exe executable that converts the eye-tracker output from edf to ASCII format readable by MATLAB/R/Python, otherwise you will need DataViewer and its license key. It recquires windows OS.

• edf2ascALL.m script to apply edf2asc.exe to your edf files, as they come from the eye tracker. It recquires windows OS.

• examples of .edf files and its converted version to .asc

  • eye_ExpIDMTlocUL_RunID1_SubIDRoBo.edf
  • eye_ExpIDMTlocUL_RunID1_SubIDRoBo.asc

BIDS format
