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

3dAutomask and 3dSkullStrip are very different programs. If you use them on EPI datasets, you may get very similar results. If you use them on anatomical (T1-weighted) datasets, you will almost certainly get different results. 3dAutomask makes no attempt to strip the skull -- it just finds the largest connected set of high-intensity voxels. 3dSS is much more complicated, using geometrical information about the skull to try to locate and remove it. If the skull is very dark, as is common in fat-suppressed EPI, then the two programs may end up the same. But that is not guaranteed.
