Hi John
they are guaranteed to have the same # of vertices, so the answer is kind
of "yes", but the thickness is not the distance between them, but rather
the distance from the closest point (which might or might not be the
"same" vertex).
You can use mri_surf2vol to sample back into the volume if you want.
cheers

Hi,
In regard to the surface files, is it correct to say that the wm and pial
vertices correspond to each other (e.g., wm vertex # 12345 corresponds to
pial vertex # 12345 as the minimum distance between the two surfaces), and
so have the same number of vertices?
Also, I would like to "colorize" voxels, but not for segmentation. Instead,
colored voxels would represent various metric "anomalies". It's rather easy
with curv files for 3D display (positive or negative values at vertex), but
I want to show this on tkmedit in 2D. Could you explain what is the easiest
way to do this?
Thanks,
John
