Hi, sorry for slow reply. I had been using 2022.2.5 but it still returned the above error.
However, I downloaded the files from the link in that post you shared and it seems to be (somewhat) working! I have managed to get the calibration to work and when trying to antisaccade experiment Becca shared it seems to work so far and save data regardin ROIs (link here for anyone interested)
Many thanks!! But one thing I still can’t get to work is the validation component. The screen gets stuck when revealing the results of the validation and the task doesn’t move forward. Is validation absolutely necessary and if so is there a way to get it to work?
