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

Sure, you should be able to calculate ttests, for example using 3dTcorr1D or 3dttest++, depending on how you find it easiest to compare groups/model correlation.

After that, you should be able to use 3dClustSim to estimate appropriate cluster sizes of a given significance. In terms of estimating the smoothness of noise (its FWHM), please see this previous thread/replies:
