Dear all,
I'm attempting to align a series of structures using the CEAlign plug-in in
PyMOL due to a lack of any detectable sequence homology. CEAlign does a
good job of aligning and the fits are very reasonable. However, the RMSD
that is calculated is based only on the c-alphas that were

PyMOL's rms_cur command will do what you want. E.g.
fetch 1rx1
fetch 1ra1
# reports Executive: RMS = 34.329 (159 to 159 atoms)
# because the structures still need to be translated and rotated
rms_cur (1rx1 and name CA), (1ra1 and name CA)
# reports Executive: RMS =0.862 (159 to 159 atoms)
Thank you all for your help. Looks like both ProFit and rms_cur will do
just what I needed.
Thanks!
Tom

hi,
from the get_object_matrix output,
i can use the euler-rodrigues transformation
http://en.wikipedia.org/wiki/Euler%E2%80%93Rodrigues_formula
and get the axis and angle of rotation.
is there a way to place the axis?
perhaps from the translation vector in the matrix?
thanks
