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

P.S. -- this stuff confuses me too.

Thinking about the spaces works best for me, and realizing that the warping J(x) = I(W(x)) means that for each x in the output (master/base) grid, W(x) is computed to find the location in the source grid, at which location the input dataset I() will be interpolated.

That is, W(x) reaches out from the master/base grid to the input/source grid -- not the other way around.
