analysing data from TSV file using the eyetribe eye tracker

Hello,

We condudcted an experiment using the eyetribe eye tracker and opensesame. Trying to analyse the TSV data file, we are not sure which message relates to the begining of each trial and to all the events during the trial. It also

seems that the timestamp that is supposed to be continuous with the eyetribe messages is not correct.

I'd be happy for some help.

Attached are the experiment file and the TSV data file (converted to txt and shortened).

Thank you.

  • Which messages did you set to relate to the start and end of the trial, and to events? The only default messages you get are "start_recording" and "stop_recording". Others you need to introduce using pygaze_log items.

    As a general tip: I would strongly recommend to avoid logging ALL variables to the gaze data file. This is rarely what you want. (To be honest, we should probably remove that functionality, because people end up using it without knowing what it does.)

    What do you mean by "seems that the timestamp that is supposed to be continuous with the eyetribe messages is not correct"?
