I don't think you can do it with optseq2 out of the box. Part of it's
purpose is to randomize the sequence of the events, but you need a fixed
sequence. You can tell optseq that there is only one event and then go
recode them into two events yourself. You can test the resulting
efficiency with optseq2 or seqefficiency. You could even write your own
simulation loop to get the one that gives you the best.

Hi,
I have a question concerning the use of optseq2 to optimize my trial
presentation. I am designing a task which consists of the presentation
of a probe followed by feedback. I am interested in jittering both the ISI
(between the probe and feedback) and the ITI (between each trial). Sadly,
my knowledge of optseq2 is quite limited and I have thus far been unable
to figure out how to accomplish this. I was wondering if there is anyone
at the NMR center would might be able to talk me through this.
Thank you for your time,
Avram Holmes
