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

Certainly the ACF parameters should be estimated from the whole brain residuals -- it is very not a good idea to estimate them from a small region.

Otherwise the normal caveat about small volume correction are still present -- were the ROIs selected via some unbiased reasoning?

Another option to consider, if it applies to your situation, is the new 3dttest++ -Clustsim option, with the appropriate mask.
