EyeLink experiment via Open Sesame PyGaze: Not recording samples data?
Dear all,
Our eye-tracking experiment using EyeLink is run via Open Sesame / PyGaze.
Currently, the resulting edf files contain both event (eg fixation) summary data and all recorded samples data. Is it possible to not write the latter samples data into the edf file, to reduce the file size a bit?
Thanks for any consideration!

Hi Elger,
Not sure whether it is possible, but I have doubts whether it is (in any case you probably have to hack into some source code, there is no option to specify what to write). Aside of that, I think it is probably better to leave the edfs untouched with all the info them, and just extract events (and not samples), via the edf2asc converter. Then you can stash away the edfs somewhere save, and only work with the ascii files for your analyses.
Hope this helps,

Hi there!
You can change these settings in the EyeLink computer.
Set options --> File Data Contents --> Untick samples
