Hi, there,
mri_surf2surf resamples one CorticalSurface onto another.
If I have two subjects from different time points (tp1 and tp2), I'd like to compare the FreeSurfer analyzed surface data. For example, could I use mri_surf2surf to resample the white matter surface of tp1 onto tp2, so I can overlay the white matter surface of tp2 to tp1 using tkmedit?
Thanks!

you have to register one to another using bbregister, fslregister, or spmregister. You can then run mri_surf2surf specifying --sval-xyz surfname and specifying --tval-xyz to get and output surface (instead of a scaler file). You will also have to spec the registration you created above with --reg (or --reg-inv).
Note that the number of vertices will be different, but you should still be able to load it into tksurfer.

Hi Guang,
If you have the same subject and two timepoints, you might want to look at the longitudinal stream.
