Hi Al, you would need to go through the Python API:
python rms=cmd.align("mob////CA","tar////CA", quiet=0) print rms python end rms contains a tuple with various parameters related to the superposition. The first value in the tuple i.e. rms[0] should be the RMS value.

Hi, I am trying to compute the RMS between a PDB file and a Gromacs trajectory. I can see that "align" does things correctly when: align trj, pdb1, mobile_state=1 i. e., when I align the first snapshot of the trajectory with the PDB file. I also understand that PyMOL does compute the RMS along the trajectory if I simply: align trj, pdb1 as it is told in: http://www.pymolwiki.org/index.php/Align However, I am unable to get the list of RMS values printed out. How could I do that?
