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

Hey AFNI gurus,

I have recently encountered the 3dLocalACF function, and been interested in its various outputs. This interest has led to a few questions (predictably). The help notes state that this program is experimental - should I expect any dramatic changes in the near future?

A second, perhaps more interesting question, is how time is used in 3dLocalACF. I've found that the program requires 39 timepoints - is there a particular reason for the 39 TR boundary - something like the stability of the a,b,c estimates?

Thanks folks - it's still fun to find a new AFNI tool that does exactly what you want that you never knew existed.
