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

You may want to take a look at some alternative ways to align across sessions:

[afni.nimh.nih.gov]
[afni.nimh.nih.gov]

One method addresses your specific request. I suspect you are running into a case where the overlap among anatomical datasets is partial, and 3drotate is assuming the grid of the original dataset. AFNI has several methods for applying transformation matrices (3drotate, 3dWarp, 3dAllineate, @auto_tlrc, adwarp and align_epi_anat.py) I recommend taking a look at the webpage I posted and the align_epi_anat.py script help.
