What are you trying to achieve?:
I’m trying to design an experiment with a 5x3 conditions - face expression intensity (0%, 25%, 50%, 75%, 100%) by time between stimulus 1 (T1) and stimulus 2 (T2) (300ms, 500ms, 700ms). Each cell contains 20 trials, i.e. we have 300 trials in total. All trials in each cell contain different T2 stimulus (10 female images and 10 male images). Each trial contains 2 experimental stimuli (T1 and T2), and 15 distractor images. I was wondering if there is a simple way to make this happen with builder, or would I have to create 300 different trials by hand?
Apologies in advance if this is a stupid question. I’ve only just started PsychoPy.
What did you try to make it work?:
I watched some youtube videos of the official PsychoPy team, but most example experiments seem to be quite simple.
I tried to make an excel conditions file with parameters for distractor, t1_file, t2_file, orientation (either 90 or 270 degrees; the task is to determine the orientation of T2), and corrAns (either ‘left’ or ‘right’; so whether participants got the orientation of T2 right). This is as far as I got and then I didn’t know how to proceed. 
Any help, or redirection to a similar solution would be immensely thankful.
What specifically went wrong when you tried that?:
