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 Rick,

the problem is that they did not supply any head motion estimations for the 7T data at all.
However, after checking the data more, it looks as if their so-called minimally preprocessed data already included a perfect motion correction.
When I run through the single volumes, the brain looks almost perfectly static, i.e., there is almost zero motion.

This is what they state in their manual:

FLIRT-based motion correction using the “SBRef” volume as the target (Smith SM et al., submitted).

I just didn't expect that their motion correction would be so good. Maybe after all motion correction or even censoring in AFNI is not required.
