I’m guessing you currently have two rows in your excel sheet, with details for A and B, then nReps set to the number of trials you want? You could fix the number of As and Bs by creating as many rows as you want trials in the excel sheet, just copying the A and B rows as many times as you want each …

I need all of the stimuli for every participant and I need the order of them to be randomized diffe…
