Hello there,

I am very frustrated with a very simple command, let me show:

PyMOL>rms (out and not hydrogen), (018.none_neutral.pdb_NEW and not
hydrogen)
ExecutiveRMS-Error: No atoms selected.
PyMOL>sele r, (018.none_neutral.pdb_NEW and not hydrogen)
 Selector: selection "r" defined with 20 atoms.
PyMOL>select o, (out and not hydrogen)
 Selector: selection "o" defined with 20 atoms.
PyMOL>rms o, r
ExecutiveRMS-Error: No atoms selected.

As you can see, I can select properly but no way of using 'rms' command.

Or "help rms" is missing something?

PyMOL>help rms

DESCRIPTION

    "rms" computes a RMS fit between two atom selections, but does not
    tranform the models after performing the fit.

USAGE

    rms (selection), (target-selection)

EXAMPLES

    fit ( mutant and name ca ), ( wildtype and name ca )

SEE ALSO

    fit, rms_cur, intra_fit, intra_rms, intra_rms_cur, pair_fit

Thanks

Alan
