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

Another trick that I've found very helpful with noisy T1 images is to use @clip_volume to create a box (everything outside the box is set to 0) as small as possible around the brain thus manually removing as much of the noise and nonbrain tissue as possible. It has helped enormously when I was skull stripping noisy T1s as 3dSkullStrip had very little to cause it to expand the mask outside the brain.
