Hi again, is it possible to use mri_convert with a register.dat to create a .mgh volume in the registered space?

any help would be appreciated... thanks! Gari

Hi,
I want to obtain volume statistics from a ROI in fsaverage.
I have register.dat and a .nii file (the ROI), but I don't now how
to get to the .label.

The last try has been:
mri_vol2vol --mov $SUBJECTS_DIR/fsaverage/label/ROI.nii
--o $SUBJECTS_DIR/fsaverage/label/ROI.mgh
--reg
$SUBJECTS_DIR/fsaverage/mri/transforms/my_own_register_created_with_bbregister.dat
--targ fsaverage

(but it is failing, error:
corRead(): can't open file $SUBJECTS_DIR/fsaverage/COR-.info)

My next steps were:
cor2label (in fsaverage)
mri_label2label (per every subject)
mri_segstats (per every subject)


Is there any simpler method to accomplish the same? Or at least
that it works?
many thanks,
Gari
