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

We almost never do this kind of correction on EPI datasets, and then only for alignment, not for the GLM analysis. Unless there are very strong shading or coil artifacts, I would avoid doing this. If you do want to use it in our standard pipeline, afni_proc.py does include an option to unifize the EPI data only for alignment with "-align_unifize_epi yes".
