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

Hi Afni Experts,
As a follow up I switched groups A and B and also switched to AminusB. In this case I got group A >B which matches the raw data values. For some reason when I use BminusA and have groups BAnd A switched (effectively the same thing), the Tstat directionality is reversed of the raw data. Could this be a bug?

Thanks,
Ajay
