Hi Guido

bits of dura or skull that are left by the skull stripping don't matter *unless* they mess up the surfaces in the vicinity (e.g. by being included in the pial surface or creating topological defects that are incorrectly fixed).

cheers

Hi Experts

I'm using Freesurfer to quantify some subcortical volumes and cortical
areas.

I have been preprocessing my data using 'recon-all autorecon1'
I have a question About Skullstripping. It is leaving a little bit of dura
behind the head. I found '-gcut' which is useful to solve it but it has some
cons.
I don't want to view the data, I just want to get the quantifications, so I
wonder if this pices of dura could affect the '-tessellate' step.

I'll be grateful if you can help
Being all for now, I await a reply
