Hi James, Regarding the AssignBondOrdersFromTemplate() method: As far as I understood, the PDB reader assigns bond orders to the amino acids in a protein, but if a ligand is present it puts all bonds of it to SINGLE bonds as auto bond-type perception is not trivial (see Roger's comments).

Hi James, Okay, now it's clear. I somehow (wrongly) thought the PDB reader would give you the protein and the ligand as two molecules and then it wouldn't have been a problem... I will discuss with Greg on how to best do this and get back to you. Best, Sereina 2013/10/25 James Davidson

Hi Greg (et al.), Thanks for the beta! I have been going through some of the recently-added functionality, and had a couple of questions regarding the PDB reading / writing. 1. Do I remember correctly that there was a proposal (from Roger) to add some auto bond-type perception to the
