[Freesurfer] Differences between mri_surf2surf and mris_ca_label for cortical parcellation

External Email - Use Caution

Dear experts,

As far as I know, there are two common ways to assign anatomical labels to cortical vertices: using mri_surf2surf (combined with an atlas annot file) and using mris_ca_label (which relies on a pre-trained classifier). My question is: in practice, which method is preferable?

Is mris_ca_label theoretically more accurate, but in reality the two yield nearly identical results? Or are there systematic, non-negligible differences? Also, is mris_ca_label less robust than the simpler projection method, particularly in subjects with imperfect surface reconstruction.

Thank you for your advice.
