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

Hello,

Adding to this thread re. smoothness estimates using first level average vs group residuals, in the Eklund et al. (2016 PNAS) paper, the authors note that the group smoothness used by 3dClustSim may be too low (compared with SPM and FSL), because (unlike SPM and FSL) AFNI averages smoothness estimates from the first-level analysis.

In light of this, would it not be more preferable to use residuals form the group analysis to estimate the smoothness?

I appreciate your help clarifying this.
