you need to call mris_make_surfaces directly. It's a bit complicated as you
need to intensity normalize and register the hires volume to the surfaces
first. I have an example script if anyone is interested, but no one has
used it yet but me I don't think (unless Matt Glasser has gotten his
version working, which on second thought he probably has)

Hi Bruce,
Is there a flag for this on recon-all? Or do you need to use
mri_make_surfaces directly?
Best,

Hi Joshua
yes, we already have upgraded mris_make_surfaces to take higher
res data
and refine the surfaces with it. Haven't tried it on the aseg
yet, but if
you upload a sample dataset I could see how hard it is.
cheers
