[solved] No pupil data in output for Eyelink

edited April 2016 in OpenSesame

Hello,

I have been having an issue with not getting the pupil data from the Eyelink setup I am using. It is the Eyelink 1000. The weird thing is that I have used a different Eyelink 1000 setup with the same opensesame experiment and I got the pupil data just fine. I did both installations of Opensesame but I'm wondering if there's possibly a plugin or module I may have missed? Or potentially there might be something related to the setup of the Eyelink I am currently using. Any thoughts or suggestions would be really helpful - sorry if the question is so vague. Thank you!

    Hi Mikael,

    Are you talking about pupil size data, position data, or both? Could you copy a line from your logfile? For example one that starts with EFIX. I suspect this to be something related to the Eyelink setup rather than OpenSesame, but I can't be sure yet.

    Cheers,

    Josh

    Hi Josh,

    I was referring to pupil size data. Sorry but I'm not totally sure what you mean by copy a line from my logfile-I don't get any output with EFIX. I get an EDF file for analyzing in the SR-research dataviewer - when I output the EDF file, that's where I'm seeing no pupil size data.

    Hi!

    If you look at the ASCII file, is there a column for the pupil size? Also, can you find out what the pupillometry settings were? (The ASCII should tell you whether you set the tracker to AREA or DIAMETER, or maybe something else entirely in this case?)

    It sounds like an issue of how you set up the tracker rather than how you use the software. (Local changes in the setup of your EyeLink overrule the software, to allow for personal preferences.)

    Good luck!

    Yes it looks like it was related to the Eyelink Dataviewer software. Thanks for your feedback!
