AFNI Message Board

Dear AFNI users-

We are very pleased to announce that the new AFNI Message Board framework is up! Please join us at:

https://discuss.afni.nimh.nih.gov

Existing user accounts have been migrated, so returning users can login by requesting a password reset. New users can create accounts, as well, through a standard account creation process. Please note that these setup emails might initially go to spam folders (esp. for NIH users!), so please check those locations in the beginning.

The current Message Board discussion threads have been migrated to the new framework. The current Message Board will remain visible, but read-only, for a little while.

Sincerely, AFNI HQ

I would recommend that you adjust the watershed values in freesurfer's skullstrip and then continue running the rest of the freesurfer recon-all pipeline. There are details on the Freesurfer wiki Fixing a Freesurfer Skull-strip.

Another option (though I've never tried it), is you can tell recon-all to not do skull-stripping using the -noskullstrip option. I believe you can then take the last file created in autorecon1 and then skull-strip that using your choice of tools (3dSkullStrip, bet, etc). Then continue on with autorecon2 and autorecon3.

Skull Strip (-<no>skullstrip)

Removes the skull from mri/T1.mgz and stores the result in
mri/brainmask.auto.mgz and mri/brainmask.mgz.
Runs the mri_watershed program. If the strip fails, users can specify
seed points (-wsseed) or change the threshold (-wsthresh, -wsmore, -wsless).
The -autorecon1 stage ends here.

When in doubt, I find the Freesurfer Mailing List to be excellent.
