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

How nonlinear?

3dAllineate does have some weak nonlinear ability, and it should work with 2D images.

3dQwarp has stronger nonlinear warping abilities, but I've never tested it with 2D images.

If you want to warp a 2D image to fit into a 3D volume somewhere (that is, have it find the right slice) -- well, good luck with that.
