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

Hi,

After looking through the afni_proc.py script, it appears that the default FD threshold is set to 0.3mm, though from this twitter post (https://twitter.com/AFNIman/status/977622189712211968), reducing it further to 0.2mm is desirable. Fortunately I have a fMRI task study with a cohort of healthy adults, so I wanted to see if setting the FD threshold somewhere in the range of 0.2-0.5mm seems appropriate? I realize that anything higher is probably too lenient, especially since my cohort generally isn't prone to much motion, but I also want to ensure that I don't lose too much tDOF from censoring/scrubbing.

Thank you for the help,

Dan
