External Email - Use Caution        

Dear developers,

please, may I ask you how I can transform volume images (containing discrete region labels) from the fsaverage space into the space of a given subject, and vice-versa?

I tried the following command:
mri_vol2vol --interp nearest --mov fsaverage/mri/aseg.mgz  --o test_mask.mgz    --s test001  --targ test001/mri/orig.mg

or
mri_vol2vol   --interp nearest --mov fsaverage/mri/aseg.mgz  --o test_mask.mgz    --targ  test001/mri/T1.mgz  --lta  test001/mri/transforms/talairach.lta --m3z talairach.m3z
--s test001

but there was always a large mismatch between the transformed images and the target image.

Best regards,
Peter
