func2roi-sess bug? - Freesurfer

10 Dec 2009


      Dear freesurfer experts:
I am trying to extract roi from my fMRI data using func2roi-sess. However, I
encounter an error that I wonder might be a bug in the code? My input is
func2roi-sess -roidef l_lingual -analysis hrf -anatlabel lh.lingual
-maskcontrast AllvFix -maskthresh 0 -masktail pos -maskmap sig -sf
subjects.txt
(the last 25 or so lines of the log are pasted below). Basically, I believe
that line in the log that reads:
/fmcsm8= bold/007
should read:
srcvol = bold/007/fmcsm8.nii
The result is that the func2roi-sess routine terminates with the error
displayed on the last line:  /fmcsm8.  Does it exist?lume bold/007
Has anyone else encountered this problem? Or maybe I am skipping a step?  I
am using v4.5.0.  If it helps, I can also paste my source code that seems to
produce this error. Thanks in advance
John Richey
