Hi Eli,

no, I wouldn't. After that paper we developed a nonlinear registration procedure, which is the long one, that helps things considerably.

cheers,
Bruce

Hi,
As mentioned in a previous message, running the subcortical segmentation
takes 10-15 hours, primarily because of the Cannonical Registration
(mri_ca_register) step. However, one the freesurfer papers (Whole Brain
Segmentation: Automated Labeling of Neuroanatomical Structures in the
Human Brain) states on the very first page that it takes only 30 minutes
to label the brain. How essential is the Cannonical Registration part? Can
one leave it out and still get a good subcortical segmentation?
Thanks,
Eli
