Datamatrix to preprocess Tobii pupil data
Hi!
I am trying to build my routines and workflow to analyze pupillometry and eye tracking data, using a Tobii eye tracker. I tried to use some toolboxes in matlab for preprocessing of pupil data, but to no avail.
I saw Mr. Mathot's tutorial on using datamatrix to preprocess the data (thank you for the precious contributions by the way!) but couldn't implement it directly, as he uses eyelink parser. Is there a way to make a Tobii parser to preprocess the data with datamatrix? Alternatively, are there any suggestions for intuitive and easy-to-implement ways to preprocess the pupil data?
Thanks in advance!

Hi @Tryfonas_Bikos ,
Eye-tracking data is unfortunately very non-standard, so you often have to write your own script that parses the data and puts it into a common format, such as DataMatrix. Do you have an example of a data file so that I can see if it's easy to parse?

I am uploading 3 data files from 3 separate subjects as I get them when participants finish the Opensesame experiment. I used dropbox as the files are too large to upload here. Note that I have not included subject number, accuracy and reaction time for each trial at this point, even though I would like to include it for my statistical analysis (I don't know if this is a problem at this stage).

Please ask for any additional information. Thank you!
