  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!
