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 all,

I have a dataset for which both MPRAGE and EPI were acquired obliquely. I see the common warning about obliquity.

Do I need to deoblique the datasets to get valid results? If so, do I just need oblique the EPI (using -oblique2card), or should I deoblique all datasets (using -deoblique) or is none of this necessary? My sense was I could just do:
3dWarp -deoblique <EPI>
3dWarp -deoblique <MPRAGE>

The datasets should be in reasonable register to begin with.

Thanks,
Matt
