[Freesurfer] optseq2 malloc memory / matrix rank-deficient

2013-05-13 Thread Koolschijn , Cédric
Dear FS-experts, I've been using optseq for many years without problems, however, I run into a couple now. My code is the following: optseq2 --ntp 255 --tr 2.0 --tprescan 4.0 --psdwin 0.0 16.0 1 --ev Gain2 5.0 8.0 --ev Gain4 5.0 8.0 --ev Gain6 5.0 8.0 --ev Gain8 5.0 8.0 --ev Loss2 5.0 8.0

I think you are at the limit of what is possible. You have TR=2 and Ntp=255 for a total scan time of 510sec. You have 9 event types, each 5stim+2null=7sec long, each repeated 8 times. This calls for 504 for stimulation and so only 6 sec total left for jitter. doug On 05/13/2013 05:28 AM,
