Try using mri_surf2surf with the --sval-annot flag.

Hi FreeSurfer experts,

Is there a way to move annotations from the same subject at one timepoint to another? I've tried doing this using a discrete-valued surface and using seg2annot, but, when I convert surfaces there are vertices between regions whose values are averages of bordering vertices. This ruins the continuity of each individual label with little islands of various values. Is there a mri_annot2annot or equivalent? Thanks!

Hi Andrew,

not sure if I understand.

The surfaces in the longitudinal directories across time (within subject) are in registration, so you should be able to use the same annotation for all time points.
