Dear freesurfer experts,
I am having a problem in extracting ROI data using func2roi-sess, and any help would be most appreciated. I wish to evaluate functional data in two ROIs that I created using mri_cor2label (left and right amygdala). Here is the command line:
func2roi-sess -roidef 54 -analysis autreg_analysis_vol -anatlabel 54 -s 20110519_12925 -maskthresh 1.3
Below, I pasted the relevant portion of the logfile produced by func2roi-sess. To the best of my understanding, at least part of the problem seems to be due to the fact that a file called COR-.info can't be found, nor can a file called "bold/001//../transforms/talairach.xfm". I've also tried it with the flag -labelspace tal (and native), but no luck.
Should these have been produced by selxavg3-sess , or perhaps I am missing a step somewhere along the way?
Many thanks, J Richey
