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

Hi John,

The short answer is no.

3dSkullStrip started off per the description of BET algorithm in Steve Smith's paper. However, it has evolved a whole lot from that. For example, it uses 3dedge detection, eye avoidance, large ventricle avoidance, non linear expansion progression, a host of convergence criteria, and it looks inside and outside the surface as it is progressing. There is also the pre-processing that is done before 3dSkullStrip starts.

Those additions were made to make the program work well on 300 anatomical datasets of various MR signal quality, and anatomical conditions.

cheers,
ziad
