I am trying to coregister the Buckner cerebellar parcellation (
http://www.freesurfer.net/fswiki/CerebellumParcellation_Buckner2011) in all my sample. However the results that I got using mri_vol2vol are not so good (see attached). Indeed in most cases the parcellation is bigger than the anatomical cerebellum of my subjects. Do you have any tips?
