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

The value in AFNI isn't in millimeters or degrees (or radians) of rotation. So using the "same" value as other software packages is fairly meaningless. You can approximate, but if you wanted roughly 3mm or 3 degrees, than you want a value of ~ 0.3 for AFNI.

If you don't want to do ANY type of motion correction, then you can remove the "volreg" block from AFNI. That's the step that actually goes through and realigns all of the individual TR images to whatever base you specify (you specified third via -volreg_align_to).
