There's this contrast named stim on the RewardProcessing task, and I am not sure of its meaning. We didn't have it in the list of contrasts in the original take of the documentation but it is there on the contrast script, see line.
By looking at the event files (see example) it looks like it refers to the stimulus' onset, ie when the two images appear on screen and the next event is the subjects response and then fixation.
@bthirion do you think we should keep this? And if so, how do we define it?
