Hi all,

We're using a tool which allows direct alteration of the pial surface (http://sites.google.com/site/vxxsoftware/) resulting in another ?h.pial file being created. We've found that it is a good way to both decrease and increase the pial boundary where there are errors. The current procedure is to use mris_fill once the surfaces are created and then apply this to the brainmask.mgz before re-running recon2.

I was wondering if it was possible to recalculate the surface stats based on an altered ?h.pial file without running recon2 again? The reason being is that if the surface is extended rather than reduced then it will not necessarily appear in the updated pial surface.

Any help would be greatly appreciated.

Many thanks,

Dominic
