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

3dBlurToFWHM is designed to work on the noise in FMRI time series, and it smooths the residuals of the time series after removing a trend to get something like the "noise".

For PET images, where the concept of time series is less applicable, you could try using 1 input image at a time. See what the results look like. However, I'd have to think about it more -- but it's time for some eggnog with rum.
