Dear Julian
You can also try the PDB plugin which places each chain into a selection
automatically for you.

Hi Julian,
A one-liner to create chain selections looks like this:
for c in cmd.get_chains(): cmd.select("chain_" + c, "chain " + c)
PyMOL doesn't provide access to the PDB header fields. In principle PyMOL
provides a way to access everything inside mmCIF files, see:
https://pymolwiki.org/index.php/Cif_keepinmemory
However, instead of doing this, I recommend to use the PDBe web API which provides the
data in a friendly JSON data structure. I've attached a Python script which creates
molecule (or chain) selections for 5n61 as an example. I recommend to load PDB structures
from mmCIF or MMTF format, which not only have chain identifiers, but also molecule
identifiers ("segi" field in PyMOL).
Hope that helps.
Cheers,
Thomas

Dear all,
I have a pdb-file with multiple chains (5N61).
Is there an easy way to create selections for all the chains that are defined
in the pdb-header (A to U) without doing it manually for every chain (select A,
chain A)?
Is it also possible to use the MOLECULE information from the header to name the
selections?
Thank you in advance,
Julian
