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

Try using it with the -retrend option. 3dFourier removes a linear trend in the data prior to filtering; -retrend returns it. Without a mean to the timecourses, EPI data look like random pixelated garbage. I'm not sure about the 'looking off center', but would bet it will be fixed as well.
