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

I'll echo Gang's answer about using the residuals from 3dMVM as likely the best option.

Years ago, 2014 apparently - I did a similar approach to what you proposed of estimating smoothness with 3dFWHMx in this paper: [www.ncbi.nlm.nih.gov]

That was of course early in the entire cluster exploration process and would still say is a valid approach, especially if you're conservative in your cluster sizes and p-value thresholds. I had also evaluated these data using permutation methods and found the results to be rather similar.
