Hi Shane
by far the best way to do this is if you have a T2 or FLAIR scan that is high-enough resolution (i.e. around 1mm isotropic).
If not, you can try the graph cuts skull stripping option in recon-all. It is more aggressive than the watershed (which is the default).

Hi Freesurfer Users, I am checking my data and there are many scans with a bit of dura being captured as GM. I have attached some screenshots below. This happens in more than 50% of my subjects. I am removing them manually them using Freeview, then running the autorecon-pial. But this will take a lot of time on 200+ subjects.. Does anyone have any tips to deal with these little inclusions? Thanks =)
