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

I noticed that the default warp type for 3dAllineate when using align_epi_anat.py is '-warp aff' (affine / 12 parameters). I was wondering why this default was chosen over other options such as '-warp shr' (rigid-body / 6 parameters)? For instance, are there benefits to using the affine_general warp type since it acts as a sort-of simple field-map correction?
Thanks!
