Attached is a SuperLab experiment in which I am trying to randomly present 24 pictures (half with an audio startle probe) and 23 ITIs (with 12 having audio startle probes). The startle onsets are also random, and I am having difficulty presenting the correct number trials for each condition. For example, when looking at the saved log file, I am seeing a number of PictureStartles that is different than 12.
Any help would be greatly appreciated. (I have not included the picture files for copyright reasons; I hope this is not an issue.)
