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

Dear afni experts,

In longitudinal studies, MRI and fMRI images of a subject at different time points were collected.
We can normalize the anatomical images independently as in cross-sectional studies.
However, this method neglect the within-subject information in spatial normalization.
There are longitudinal pipelines for morphology measures such as in freesurfer.

Do you think it is necessary to optimize the registration in longitudinal fMRI studies?
if so, is it possible to optimize the registration issue in longitudinal fMRI studies using existing tools in AFNI?


Thanks very much！
-LZ
