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

Yes, '-cost ls' is very similar to 3dWarpDrive's or 3dvolreg's cost functional, and is appropriate for registering 3D images that are "similar" in appearance. If you are registering dissimilar images (e.g., EPI to T1), then you should use another cost functional.

In many cases, it is better to use the script align_epi_anat.py rather than 3dAllineate directly -- despite its name and help file, it can actually drive the registration of anat to anat (for example).
