Dear Freesurfer community,
I would like to get a better sense of how mri_em_register and mri_ca_register work. I understand the former is a linear registration and the latter is nonlinear, and that they are both meant to register an individual to a template space (MNI152?).
Would it be possible to update the wiki pages to give more information about the algorithms and cost functions used and other such details? And to provide references to the literature in support of the algorithms if possible?
Thank you. Best regards, Ruy
