I'm working with a Stable 4 version of FreeSurfer.
I think your explaination about the vertices is acctually the answer to my
question. The variation that I'm seeing between the pre-masked, and
non-pre-masked surface is quite small, but never-the-less present. If
this is the case, I think t
What version are you using? I just checked this on my current version
(and this part has not changed in a long time), and it gave the same
result in the mask regardless of whether I masked the input or not. One
thing that I did find is that it will smooth the vertices that are
outside the mask
You are correct, surf2surf is not changing the values from out side the
masked region. However the problem is that in smoothing the values inside
the masked region surf2surf appears to be incorporating values from
outside the masked region (even if its not smoothing these "outside"
values).
mri_surf2surf will not change the values outside of the mask (those will
be left unsmoothed). Is there an actual difference in the mask?

Hi,
I want to smooth a cortical thickness map using values only in a specific
area. Basically I want to mask out all other segmentations, for example
smooth with fwhm of 20 only in the postcentral region.
I've used quite a few combinations of the -label-src and -label-trg flags
and noticed
