I think if you convert the afni's skull stripping to .mgz format and put
it in mri/brainmask.mgz we will recognize that it is different from
brainmask.auto.mgz and use it instead

Hi, I am just following up on my previous question.
The -gcut does not appear to make any difference on our skull stripping. I
also saw that you can change flags for watershed option. Do you recommend
this? If so, how would you implement this on freesurfer output that was
already run?
We achieve fairly good skull stripping with this dataset using afni's
skullstrip function. Would it be possible to enter the already-skull
stripped data into freesurfer? if so, how would you set this up? Right now,
I am entering the original dicom files as input to freesurfer -- is it
possible to use other file formats as input?
Thanks!

Hi,
Thanks for your response. Maybe I am
missing something, but I haven't been
able to find any documentation about how
to use graph cuts skull stripping
in the freesurfer pipeline. can you
please advise?
Thanks,
Michelle

Hi Michelle
you can try using the graph cuts
skull stripping. It is more
aggressive and more likely to
remove more skull/dura (and also
to remove some brain)

Hello,
We have assessed freesurfer
output for 160+ brains,
and about 50% have poor
segmentation of pial matter
that includes too much
skull. Manual edits and
re-running does work to
improve the problem, but is
very time/labor
intensive for so many scans.
I saw on the freesurfer wiki
that you can include T2
or Flair images to
improve the segmentation for
this problem. However,
we do not have these
extra scans. What do you
recommend to do otherwise?
Thank you!
