Hi Phoebe,
Sorry, but I didn't actually comprehend that you
wanted something other than the main parameter
angles that a typical factorization would generate.
Paul Taylor set me straight. Bringing up the z-x-z
and related order conventions clarified it.
So then to back up, I believe that we do NOT have
a tool to generate the formal Euler angles. The
afni_util.py angles should basically match the
parameters applied in 3dAllineate, but not the
rotating frames of reference.
What do you actually need the Euler angles for?
Maybe that is something that could be added.
