Hi,

I'd like to convert a subject's aparc+aseg.mgz to mni305 (2mm) space. So, I ran the following commands (FS 5.1):

(from subject's mri directory)

mri_vol2vol --mov orig.mgz --tal --s $SUBNAME --o orig.mni2mm.mgz mri_label2vol --seg aparc+aseg.mgz --o aparc+aseg.mni2mm.nii.gz --reg orig.mni2mm.mgz.reg --temp orig.mni2mm.mgz

The volume orig.mni2mm.mgz looks totally fine, but the aparc+aseg.mni2mm.mgz is way off -- it is shifted anterior and superior relative to the orig volume. I double-checked orig.mgz and aparc+aseg.mgz, they are totally fine and line up. I also tried this:

mri_label2vol --seg aparc+aseg.mgz --o aparc+aseg.mni2mm.nii.gz --regheader orig.mgz --temp orig.mni2mm.mgz

This also did not work. Can anyone point out my error?

Thanks in advance,

Tim
