[Stefano-Trapani]

PyMOL 2.5.0 Open-Source, 2022-03-17

Tested on PDB entry 1a2c.
Tested on both PDB and mmCIF files (with connect_mode either 0 or 4).

select polymer leaves out 2 out of 4 residues from chain J (which contains non-standard amino acids).

fetch 1a2c, async=0
show lines
hide everything, (not (c. J and not solvent))
zoom visible
set seq_view
select 1a2c_J , 1a2c and c. J and not solvent
select 1a2c_J_poly , 1a2c and c. J and not solvent and polymer
