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

Giuseppe,

My bad. You are totally right, I did not think about the situation carefully. The two operations are not commutable because the scaling is different for each voxel (I forgot this when I imagined the switch between the two operations).

So it is probably better to do spatial blurring first, and then normalize the result.

Thanks,
Gang
