Dear FreeSurfers,

 

I'm having a little trouble getting something that works in optseq to work
in optseq2. Here's what' is going on . . . when I run this command, things
work fine and I get 6 nice sequences:

 

optseq -ntp 170 -TR 3 -npercond 4 4 4 4 4 4 -tpercond 17 17 17 17 17 17
-label NgReal NgLook NgPhoto NuReal NuLook NuPhoto -nsessions 6 -nruns 1
-timewindow 20 -prestim 4 -nsearch 50 -o OptseqTEST

 

However, when I run this command (i.e., my best translation of the previous
command into optseq2), I get an error saying that all my schedules are
ill-conditioned and I need more scan time or fewer repetitions:

 

optseq2 --ntp 170 --tr 3 --psdwin 0 20 1 --ev NgReal 17 4 --ev NgLook 17 4
--ev NgPhoto 17 4 --ev NuReal 17 4 --ev NuLook 17 4 --ev NuPhoto 17 4
--nsearch 100 --nkeep 6 --o Optseq2TEST

 

Is this a substantive difference between optseq and optseq2 or did I make a
mistake with my optseq2 command? Also, I'm assuming there is a reason why I
should use optseq2 rather than optseq, but I don't know what it is. Can
someone clue me in?

 

Thanks!
