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

Leah,

> Are the AFNI ACF blur estimates supposed to be using stats.s####_REML file as the final dataset?

Conceptually ACF/smoothness estimates should reflect the spatial relatedness in pure "noise" because you're supposed to control "false positives" assuming there is no signal in the data under the traditional statistical framework. So, it may make more sense to use the model residuals at the subject or population level to estimate the ACF parameters.
