[PyMOL] creating objects from pdb w/out chain id

[Hanspeter N. <nieder@OCF.Berkeley.EDU>]

I'm trying to create an object of a protein from a PDB file that doesn't
give a chain ID (pdb is 1BG2).

I normally do something like:

create atub=(/1jff//a/)

to pull a specific chain out of a PDB file, but 1BG2 doesn't have a chain
name.  And if i use "create kin=(/1BG2////)", the object kin gets ALL the
elements from 1BG2, including the waters, nucleotide, and ions, which is
exactly what I'm trying to not do.

How can I create an object out from a nameless chain?
