Problem Tobii X3-120 with Pygaze(Opensesame). PupilSizeRight/Left =-1 2times over every 3
I have tried to run an experiment in Opensesame with pygaze. I have a Tobii X3-120.
I notice this problem when I open the output file:
Every 3 measure, PupilSizeRight/Left have value "-1" for 2 times. I attach the image of the top of the data file. The rest of the file looks the same
Do you have any suggestion?
