Thanks, but this is not what I meant - the attached csv file is what I already know how to do...
My problem is that on some blocks I want to present only some of the stimuli (e.g., i have a total of 20 stimuli, but want to present only 8), and in a random (with no replacement) order. That's why I have to use a stimlist, and that's why I need to connect correct/incorrect responses to the stimuli in the stimlist.
