Sorry if this is a repost.
I have a set of subjects whose pial surfaces are poorly reconstructed because of bad gray/csf contrast. Specifically, the pial surface doesn't seem to deviate from the white matter surface by much more than .5-1 mm. Is it possible to artificially "grow" the pial surface or create an artificial pial surface that is a set distance from the white matter surface (say 2.7 mm).
Thanks for the help! Jeremy Skipper
