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 Kristina,

It is just there as an additional option.

Some people use only motion derivatives, some only motion
parameters, some use both. The option was added to allow
capturing more of the motion effect in the case of resting state
analysis, but it does not necessarily produce a big gain. It is
less of a question in task-based FMRI.

In any case, we do not say that everyone should be using it.
It is simply available.
