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

Fair enough, but the call to cat_matvec is described as catenating the volreg and epi2anat transformation, but it is catenating the anat2epi transformation with the volreg one.

Adding the -I option after an input in cat_matvec will invert the transformation matrix. So while the file is the anat2epi transform, the inverse is the correct epi2anat transform.

You can (and should) always check the alignment using AFNI or @AddEdge.
