Hi, I was wondering if it is possible to use optseq2 to get null events (e.g. fixation) between each event type. I would like to see the optimal sequence of trials for a design that involves two event types (each 0.5 sec), 60 TRs for one event, 26 TRs for the other, and a 2sec TR. I would like to have an intertrial interval lasting between 2-10 seconds (jittered) between each of the 0.5 sec long events. I can’t seem to find an option for optseq2 that would allow me to set a null event between each 0.5 sec event. Is this possible and if so what options should I use?
Thanks! Anita
