Hi, I am having a related problem: I don't want 0-events that last longer than a normal trial (2 sec) and lead to the fact that the number of a TR (2sec) in the run is not equal to the number of trials. Setting --tnullmax 2 produces an error:
ERROR: could not enforce tNullMax (ntries=100000) ERROR: syntheszing schedule Does it make sense to use optseq with this many restrictions at all? My command: --ntp 200 --tr 2 --psdwin 0 20 2 --ev singles 2 30 --ev pairs 2 30 --ev unquads 2 30 --ev orquads 2 30 --ev news 2 30 -- tnullmax 2 --nkeep 4 --o exp --nsearch 10000 Thanks, Kathrin On Oct 20, 2009, at 12:09 PM, 杨宏宇 wrote: > Hi list, > > I am using optseq2 to design my fMRI study.
