Erasing Stimulus at the END of a sequence of trials

Group: Forum Members Posts: 28, Visits: 164	Hi, I have a series of trials and likerts that branch from one to the next. I want to keep an image on in the background of all of these trials and then be removed at the end. Originally I just reset the stimulus for each trial / likert but this meant that there was a blank frame in between each branch so instead I have the pictures erase value set to false. This works just fine but I am not sure how to erase it at the end of this sequence. Since I am running this sequence many times in a block will this just mean that new images layer over each other and take up more and more ram as the sequence goes on? Thanks in advance for your help :)

Thanks in advance for your help :) You could end each sequence with a trial that does nothing but erases the screen. <trial erasescreen> / stimulusframes = [1=clearscreen] / validresponse = 0 / trialduration = 40 / recorddata = false </trial> or you could clear the screen in whatever the first trial in the sequence is (thus erasing anything left from the previous sequence). <trial first> / stimulusframes = [1=clearscreen, mypicture] ... </trial> > Since I am running this sequence many times in a block will this just mean that new images layer over each other and take up more and more ram as the sequence goes on? No.
