Re: [Freesurfer] func2roi-sess bug? - Freesurfer

14 Dec 2009


      Ok - I believe I figured out the problem, but I wanted to post it to the
list, so that anyone else who encounters this error can hopefully spend less
time than I did tracking down the culprit!
Essentially, a break was being passed inappropriately to the mri_vol2roi
subroutine called by func2roi-sess. The break (return/enter, etc) was
located in the .txt file that specified the run numbers that I wanted to
analyze (in my case, 007 008 009). These strings were separated by a space
and a break, which caused the srcvol to equal
srcvol = bold/007
/fmcsm8
And this caused func2roi-sess to terminate with errors when it couldn't find
such a file.

that is bizarre. What version of freesurfer and what operating system are
you using?

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
