Function Documentation

void core::chemical::gasteiger::assign_gasteiger_atom_types	(	core::chemical::ResidueType &	restype,
		GasteigerAtomTypeSetCOP	gasteiger_atom_type_set,
		bool	keep_existing
	)

Assign gasteiger atom types to the atoms in restype. If "keep_existing" is true keep any already-assigned types Otherwise assign all new types.

Remaining issues:

• Input with explicitly mentioned aromatic bonds is not necessarily handled correctly. ** (I haven't extensively tested these yet.)
• Oxygen typing in aromatic rings is still an issue. ** While most work, N-O-N bridges like in PDB ligands G98 and 3C3 are missed. ** Conversely, methylated/oxidized dibenzofurans like in KRC and FCM are mistyped as trigonal when they're not.
• Rosetta needs to have formal charges notated. (Cannot calculate them from the number of hydrogens present.

Differences from gasteiger types which aren't necessarily errors:

• Phosphooxime oxygens like SEH & CGT are typed trig versus gasteiger tet.
• Carbamoyl oxime oxygens like GHR and VPU are typed trig versus gasteiger tet.
• 5 member ring oxygens where there's an exocyclic double bond like PHX and FUR are typed trig versus gasteiger tet.
• 5 member carbamoyl oxygens like CLW and A91 are typed trig versus gasteiger tet.
• The nitroperoxide oxygens of 16X are typed tet versus gasteiger trig
• The bridge nitrogens of fused ring structures like PO5, C7M and AZQ are typed trig versus gasteiger tet.
