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

You could try the 3dIntracranial program. It works about 80-90% of the time, at least on T1-weighted images (MP-RAGE and SPGR styles of acquisition). I don't know how well it would work on angio data. If you have a T1-weighted structural, you could try 3dIntracranial on it; if that works, then you could use that as a mask (e.g., via 3dAutomask and 3dresample and 3dcalc) to mask off angio datasets.

I take it that you want to do projections (via the Render plugin) on the angio data?
