Bruce,
Thanks for the pointer. What is happening is we would like to combine
the skin/skull/CSF volumes with that of the cortical segmentation. The issue we
are having with the output of mris_fill is the volumes are now different sizes
than the aseg output from recon-all.

Hi Matthew,
yes, you can use mris_fill to fill the interior of a topologically correct,
closed surface. You'll need to run some boolean operations on them to get the
volumes you want, but it should be pretty easy I think.
cheers
Bruce
