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

Thanks, that is mildly illustrative that the situation is: adding the covariate makes that swath have notably larger-magnitude values than the surroundings, rather than it shrinks values outside the swath.

I am still not sure what would cause this. Some kind of outlier-ish interaction with values? Might have to look at the data to investigate further.
