[Chimera-users] "ligand" category for selection

Just a note on the automatic "ligand" category: a small molecule by itself would not be identified as ligand, only when it is in the same model as a macromolecule. The automatic category heuristics are here:
Your own specifier would (of course) be based on your advance knowledge of what structures are going to be processed, not just what you want the specifier to include, but also what other stuff might be present that you wish to exclude.
