Pupil preprocessing in Matlab

Preprocess EyeLink pupillometry data using the FieldTrip toolbox Open the pupilTutorial.ipynb for the full Jupyter notebook (see https://anneurai.net/2015/11/12/matlab-based-ipython-notebooks/)

Several of the functions you'll need, for edf2asc conversion and reading in asc files, can be found in my Tools repo https://github.com/anne-urai/Tools/tree/master/eye. Make sure to download all of them, and to ensure the edf2asc is executable by nagivating to the path with the file in Terminal, and typing chmod +x edf2asc.

The first section of the code is specific to EyeLink (edf) files. See here https://github.com/anne-urai/pupil-memory/blob/master/code/processPupilData.m for a similar approach, but using files from SMI eyetracker (which have to first be converted using BeGaze).
