I added 120 to the ntp make ntp=300, but still got the same error. I also tried running a ntp=360 and got the same ill-condtioned statement.

Ie, your total run time is 180*2=360 sec. The total stimulation time is 12*10*3 = 360 sec. You need to increase the length of the fmRI run (or reduce the total number of stimuli). Usually I include as much fixation as any other condition. In this case, that would be 12*10=120 sec. So try adding 120 sec (ie, incrase --ntp 180) and re-run On 12/19/2017 05:21 PM, Dirks, Bryce Ronald Alan wrote: > > Hello, > > I am trying to create the optseq for a cognitive flexibility > experiment we are conducting.
