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

The best solution is to go back to the intermediate files and re-run the processing from there with the correct smoothing level. Filters are additive, so if you now applied a kernel of 4mm or 8mm, you'd end up with different values than you would have otherwise doing it in a single step.

One could make an argument of using 3dBlurToFWHM, but I would say go back and do it again. You could modify the afni_proc command to start at a different point. Some indication of what you'd need to do are in this blog post. If you need more help, post your current script and we can try to modify it for you.

I should have set FWHM=8mm, however, the default afni_proc.py was 4mm
