Dear Freesurfer experts,
I have a manual segmentation of a certain brain feature done in Freeview. I want to pool these segmentations from different subjects to create some kind of a heat map/probability map.
In order to do this, I assume I need to convert my segmentation to a volume first (In my case the Talairach space); hence, I tried:
mri_label2vol --seg example.mgz --temp talairach.xfm --o seg_talairach --reg example_orig.mgz
the example_orig.mgz would correspond to the original T1 which I used to do the segmentation.
But this gives me the error message:
ERROR: could not determine type of talairach.xfm
ERROR: reading talairach.xfm header
Where is the problem?
Many thanks!
