Hi again,

So many questions!!

Is there some sort of correspondence between vertices on the inner (wm) and outer (pial) surfaces? Ie., for every vertex on the inner surface, is there a point on the outer surface, and if so, does Freesurfer retain this information in any of the files?

Also, I have some binary masks that I have manually traced using another program that I would like to apply to the surfaces to get regional measures of thickness. The mask images are in analyze format. Is there any way that I can do this?

Thanks as always,

Alex
