[phenixbb] Using phenix.pdbtools to strip multiple conformations out of a PDB file?

[Stephen Graham]

Dear all,

Apologies if this is a dumb question, but I couldn't find the answer
in the docs or by asking the googlebrain.  Is there a simple way in
phenix.pdbtools to strip "alternate conformations" of side chains,
etc, from an input PDB file?  By removing "alternate conformations" I
mean I would like to keep the conformation with the highest occupancy
(not necessarily denoted 'A' in the altLoc column) unless all
conformations have an equal occupancy, in which case I'd arbitrarily
keep conformation 'A'.

I think it should be possible by a clever atom_selection command, but
the correct syntax has thus-far eluded me!

Thanks,

Stephen
