I am having a problem with selxavg3-sess (for FS 4.5) where it is giving me
an Ill-conditioned error that I can't trace out.
I have 8 runs that I am running separately (same basic analysis for each
run, but each run gets it's own analysis for svm purposes). Originally for
this subject, I created an analysis and it ran fine for all 8 runs. I went
back and changed the timewindow on the analysis (and only the timewindow)
and now, while it runs fine for 7 or the 8 runs, one of them gives me an
ill conditioned error during selxavg3-sess. I double checked the paradigm
file and all conditions are listed, and the only change between when the
analysis ran fine and when it gave me this error was changing the
timewindow. The mkanalysis commands I used both times are listed below.
Original analysis (worked fine):
foreach r (1 2 3 4 5 6 7 8)
mkanalysis-sess -analysis grating_nodist_ld_run${r} -TR 2 -paradigm
grating.dat -designtype event-related -funcstem fmc -motioncor -runlistfile
nodist_run${r}.txt -inorm -tpexclude tpexclude.dat -nconditions 3
-timewindow 22 -TER 2 -noautostimdur -polyfit 2
end
new analysis (illconditioned on one run only):
foreach r (1 2 3 4 5 6 7 8)
mkanalysis-sess -analysis grating_nodist_ld_34_run${r} -TR 2 -paradigm
grating.dat -designtype event-related -funcstem fmc -motioncor -runlistfile
nodist_run${r}.txt -inorm -tpexclude tpexclude.dat -nconditions 3
-timewindow 34 -TER 2 -noautostimdur -polyfit 2
end
