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 Paul,

I read your post and got curious about the default smoothing operation in afni_proc.py. It is my understanding that a 'blur' block in afni_proc invokes 3dmerge to conduct a Gaussian FWHM blur at a specified level. But from your post above it would seem that this is a sub-par way to blur. If that's the case, is there a way to implement ACF smoothing in afni_proc?
