Hi there!
I am using Inquisit 5 and the Tobii Plugin to record gaze preferences between different visual stimuli.
I would like to add a column to the eyetracker file to indicate trialnumber, the type of stimulus displayed, and the trialtype. Is this possible?

So far, I have tried to include following columns in the <eyetracker> element (in addition to the gaze, fixation, and pupil.width columns):
/ columns = (list.faces.currentvalue, script.currenttrial.currenttrialnumber, trialnum)

while I don't receive an error message, the final gaze file does not contain any of these columns.

What am I doing wrong here? The columns work when I try to include them to the <data> element

Thanks in advance -
Stefan

You need to set up markers indicating item, trial number and type. Those can be captured in the gaza data stream. See https://www.millisecond.com/support/docs/v5/html/howto/sendmarkerstotobii.htm
