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

It seems like this test might not be valid when there is true activation for both conditions, and the activation regions are close to each other without overlapping. Then we should find activation no more than p_thr of the time, but it might be the case that we are likely to find it more often than that as the clusters bleed into one another. I haven't done the math on this, but it seems like the place to look.
