Dear Freesurfer expert,
I'd like to make mixed blocked/event-related design using Optseq.
(15sec fixed block - 15sec condition 1 block - fixed block - 15sec condition2 block ....)
This below command does not seem to produce what I want.

optseq2 --ntp 129 --tr 1.5 --tprescan -9 --psdwin -1.5 21 1.5 --nsearch 10000  --ev Condition1 3 15 --ev Condition2 3 15 --ev fix 15 6 --nkeep 2 --o test

Any comment will be appreciated.

thanks,

Bumseok
