Hi Bruce,
I performed the -autorecon-pial as a means of regenerating the surfaces as
instructed on the Freesurfer skull strip tutorial. The brainmask.mgz file does
not have the skull but it has some dura left over. The issue I had before was
that the skull would re-appear after the subject fin
Hi Arsenije,
-autorecon-pial should not recreate the brainmask. Is the brainmask.mgz
currently correct?

Hi Paul,
As long as your surfaces are unaffected (no brain is missing), the dura
does not matter. Ideally, the brainmask.mgz should be /only/ brain.

Hi Rashmi,
I assume you've read the skullstrip wiki page, but I've included it below
just in case.
Have you tried different watershed thresholds? Also, you do not need to
include the -clean-bm flag every time. You can run the skullstrip step
once with the -clean-bm to start from scratch, and
Thank you Bruce,
I certainly understand your point. In my study I am trying to use whole
brain volume to normalize my volumetrics data. Due to the inclusion of the
dura into brain, I may get variation in the whole brain volume across
subjects.
In addition the current issue is affecting the grayma
Hi Rashmi
getting rid of all the dura without removing any problem is exceedingly
difficult (if not impossible). Usually we live with some remaining dura
as it doesn't affect the surface placement much.

Hi Wei-Ta
if the remaining skull and dura don't affect the pial surface then it
doesn't matter. Run it all the way through recon-all and you'll probably
find it doesn't matter.

are you really trying to run an fMRI dataset through? recon-all will only
work with T1-weighted anatomicals.

check the talairach to see if it is value, and also make sure that the
T1.mgz white matter intensities are close to 110 almost everywhere.
