[solved] Variable Interstimulus Interval (ISI)
First, thanks for making this software available: it solves a lot of problems!
I have a question about the Interstimulus Interval, particularly I do not understand how to set the duration of, let's say, a black screen between trials to variable. I see that I can have a fixed duration (ie 500 ms), but how do I specify that I would like a duration between 400 and 600 ms?
Thanks in advance and sorry if this question has already been posted (I was unable to find it)
