Hi Matt,
Did you try the -c option described in the function's help?

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.

Freesurfer,
Sorry for the repost, but I did not get any further details:We have scans that have recon-all completed. Following recon-all, we completed watershed (under the MNE toolbox) to extract skull and scalp from the T1 scans. The outputs of this algorithm are outer brain, inner skull, outer skull and outer scalp surfaces. We are particularly interested in these volumes for our study. Is there a way to convert these surface to volumes representative of CSF (layer between brain/skull), skull (inner to outer skull surface) and skin (outer skull to outer scalp)?
