External Email - Use Caution
Hi Dr Greve, I appreciate your guidance very much.
I followed your suggestion. I put lh.cerebellum in fsaverage and I ran
mri_vol2surf.
as follows:
mri_vol2surf --mov grf.th1.3.pos.sig.cluster.mgh --hemi lh --surf cerebellum
--mni152reg --o grf_onto_cerebellum.nii.gz
Now I am getting this error
ERROR: number of vertices in /FSV6.0/fsaverage/surf/lh.thickness does not match
surface (163842,34247)
Any suggestions are appreciated ;-)
John
You will have to put the cerebellar surface in fsaverage/surf/lh.cerebellum
Note use "lh" even if it is the entire cerebellum as FS commands generally
require a hemisphere.
The run mri_vol2surf specifying --hemi lh --surf cerebellum
