I am trying to use the get_dihedral routine. If I've got just one object it works as expected. For example:
PyMOL>get_dihedral 9/C, 10/N, 10/CA, 10/C (I type in) cmd.get_dihedral: -49.721 degrees. (pymol replies) But if I've got MORE than one object loaded, which I usually do, pymol gives me this error: GetDihedral-Error: Selection 1 doesn't contain a single atom/vertex. GetDihedral-Error: Selection 2 doesn't contain a single atom/vertex. GetDihedral-Error: Selection 3 doesn't contain a single atom/vertex. GetDihedral-Error: Selection 4 doesn't contain a single atom/vertex. I **need** to be able to call get_dihedral when I've got more than one object loaded. De-selecting all but one object doesn't work either. I have tried everything that I can think of. Loading multiple pdb files into one object DOES Work (and then I specify a state to get_dihedral), but again this is not what I want to do. Can someone please help me?
