Keeping image on-screen for a fixed window

[jcallaire]

I am having a similar problem, and I think my problem stems from not knowing where to put the min-max durration.

I am doing an N-back task and I want a letter to stay on the screen for 2 seconds and if no response is made I want to go to the next letter. Of course if a response is made I want to move on.

I tried all permutations of adding min/max duration, clear-1, -1 (see below) and I can’t get it to work perfectly.

0-5000! rt:1,2-1,full,clear-1

i attached the first 2 lines of my program below. Any guidance would be much appreciated.
