External Email - Use Caution
The registration registers the meshes, but it does not alter the number of vertices in them. There is no 1-to-1 correspondence between the vertices of the 2 meshes.
May I ask why you need this? What do you want to achieve?

External Email - Use CautionI'm just going to try this again, but this time with a different command:
mris_apply_reg --src-xyz /usr/local/freesurfer/subjects/fsaverage/surf/lh.white --trg /home/ian/lh_reg.white --streg /usr/local/freesurfer/subjects/fsaverage/surf/lh.sphere.reg /obd-fs/proc/my_subject/freesurfer/surf/lh.sphere.reg"
This gives me the same issue - fsaverage/surf/lh.white has 300k+ points in it, and the output of this command has fewer than half that.
I do not understand what kind of registration would reduce the number of points. What is the relationship between the first point in --src_xyz file and the first point in the output registered file? If I halved the number of points in the input, would I expect the output to be half the size? Or less?
I'm sure there's a simple explanation that I don't have my head around just yet - thank you for your patience.

Isn't that what you got from the mri_surf2surf command?
