Hi there,
I have two questions regarding Talairach registration.
_*Question 1:*_
I would like to check Talairach registration according to this page:
https://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/Talairach_freeview
I see this line for the tutorial:
freeview -v tal_before/mri/T1.mgz
tal_before/mri/brainmask.mgz:reg=tal_before/mri/transforms/talairach.xfm
And I tried to apply that to my subject:
freeview -v subj1/mri/T1.mgz
subj1/mri/brainmask.mgz:reg=subj1/mri/transforms/talairach.xfm
Freeview opens and I see the T1 but it gives an error for the brain mask:
"Failed to load MRI: <fullpath>/subj1/mri/brainmask.mgz"
Does anybody know what's going wrong?
_*Question 2:*_
Another way to do it would be to move the brainmask.mgz file into
Talairach space and save it and then load that volume (let's call it
brainmask_moved_to_tal.mgz) onto the FS Talairach subject.
2a: How do I move brainmask.mgz using subj1/mri/transforms/talairach.xfm
and save the output?
2b: Where do I find the FS Talairach brain? I'm looking for the
underlay that I see when I run:
tkregister2 --s subj1 --fstal --surfs
(as per instructions here: http://freesurfer.net/fswiki/eTIV)
Thanks for any insights!
Koene
