Hi Doug,
Thank you very much for the reply. The question that I have now is, how do I distribute my time points between the events and also specify a fixed number of time points for the "NULL" cases?
Thanks and Regards, Usha
you should not interpret each line as a time point. Each line is a stimulus presentation. You have specified that the presentations are 1 sec long and can occur at an time divisible by 1 sec (--psdwin 0 12 1), so you could have as many as 600 lines. BTW, I would probably go longer than 12 sec for the window, more like 20 would be better.

Hi,
I was trying out a code to generate optimal sequences using optseq2. The code is as follows:
optseq2 --ntp 300 --tr 2 \ --psdwin 0 12 1 \ --ev one 1 20 \ --ev two 1 15 \ --ev three 1 15 \ --ev four 1 50 \ --ev five 1 50 \ --ev six 1 50 \ --ev seven 1 50 \ --nkeep 2 \ --o ex \ --nsearch 10
The output file for the above code displays more than 300 lines,i.e., >300 time points. How can I modify the code so as to limit the output to 300 time points. Also, the output has all the required categories(events) till the end, Hence I could not just ignore the lines above 300.
