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 Mengxing,

No, you are correct, but it is okay, and not so obvious why.

In the anat block, the anat is always aligned to the EPI. However, due to that e2a option, the inverse of that (a2e) transformation is applied to the EPI (via the cat_matvec command using -I). That transformation is concatenated with the volreg one to prevent multiple interpolation steps.

Does that seem reasonable?
