A delayed addendum...
Some attributes are not included in the Programmer's Guide lists or
what you get from help() in IDLE:
atoms: areaSAS, areaSES, bfactor, charge, occupancy, serialNumber
residues: areaSAS, areaSES, isHet (the latter is in help but not the
current Prog. Guide list)
molecule models: display (not in Prog. Guide list for Molecule
because inherited from Model)
Some attributes do not come from the C++ layer, and some do not exist
until you do something particular in Chimera (areaSAS and areaSES are
assigned when molecular surface is generated; charge is assigned when
Add Charge is used; etc.). Also, new attributes you have created
with Define Attribute are not listed. Generally the Render/Select by
Attribute tool will list these atom and residue attributes, however.
