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

Also, question here:

> registration seems to mess up timing more than time shifting messes up registration

Does time shifting (or despiking) ever *help* registration? I ask because we might like to discard some subjects who moved too much, and plan to use the -ldfile option on 3dvolreg to do this.

Anything that improves the accuracy of the motion correction estimate (without regard to the accuracy of other data aspects) would be useful here.

Thanks again!
