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 am interested in the autocorrelation itself (as an end product so to speak). For example, I am interested at what TR (or seconds) the autocorrelation reaches or drops below 0 (first zero crossing).

How would you measure that, generally speaking? Options:
1. No motion censoring in AFNI, hence no interpolation.
2. Motion censoring in AFNI, then some kind of interpolation.
3. Motion censoring in AFNI, but no interpolation (leaving the censored TRs as zeros).
