OESplitMolComplexOptions

class OESplitMolComplexOptions

The OESplitMolComplexOptions class encapsulates properties and resources that determine how OESplitMolComplex and OEGetMolComplexComponents operate. For examples detailing how to modify and/or operate different filters see Splitting Macromolecular Complexes.

Constructors

OESplitMolComplexOptions(const OESplitMolComplexOptions &rhs)
OESplitMolComplexOptions(const std::string &ligName=std::string())

Constructor and copy constructor. If ligName is specified in the call to the constructor, components will be recognized as ligands if and only if they have a matching residue name string.

bool GetCollectProteinByChain() const

Returns true if fragmented protein chains be associated with the same the same site.

GetCombinedFilter

OESystem::OEUnaryPredicate<OESystem::OERoleSet> *GetCombinedFilter() const

GetLigandFilter

OESystem::OEUnaryPredicate<OESystem::OERoleSet> *GetLigandFilter() const

Returns a new copy of the ligand filter.

GetMaxBindingSiteDist

double GetMaxBindingSiteDist() const

Return the maximum distance from the ligand to be associated with a binding site. Can not be less than 1.0 Å.

GetMaxSurfaceWaterDist

double GetMaxSurfaceWaterDist() const

Return the maximum distance from the protein to be considered a surface water. Can not be less than 1.0 Å.

GetOtherFilter

OESystem::OEUnaryPredicate<OESystem::OERoleSet> *GetOtherFilter() const

Returns a new copy of the filter that matches everything that does not match the combined filter.

GetPromoteUnknowns

bool GetPromoteUnknowns() const

Returns true if components classified as OEMolComplexFilterCategory_Unknown should be considered the ligand if no others ligand is found.

GetProteinFilter

OESystem::OEUnaryPredicate<OESystem::OERoleSet> *GetProteinFilter() const

Returns a new copy of the protein filter.

GetSeparateResidues

bool GetSeparateResidues() const

Returns true if proteins are to be separated into individual residues before selection. Separating into residues can be used to extract binding site residues.

GetSplitCovalent

bool GetSplitCovalent() const

Returns true if covalent ligands are to be searched for and split out as separate components.

GetSplitCovalentCofactors

bool GetSplitCovalentCofactors() const

Returns true if covalent cofactors are to be searched for and split out as separate components.

GetWarnNoLigand

bool GetWarnNoLigand() const

Returns true if a verbose level warning will be generated when a ligand is not found.

GetWaterFilter

OESystem::OEUnaryPredicate<OESystem::OERoleSet> *GetWaterFilter() const

Returns a new copy of the water filter.

ResetFilters

void ResetFilters(unsigned site=1u,
                  bool surfaceWaters=false,
                  unsigned ligCategory=OEMolComplexFilterCategory::Ligand,
                  unsigned protCategory=OEMolComplexFilterCategory::ProtComplex,
                  unsigned waterCategory=OEMolComplexFilterCategory::Water,
                  unsigned modelNo=1u)

Regenerate filters based on parameters. Can be overridden by methods to set individual filters. Site 0 means all sites. ModelNo 0 means all models.

Note

It may be necessary to remove the input flavor OEIFlavor_PDB_ENDM to read all models (see the splitmolcomplex example for how to do this). In most situations, the modelNo parameter should be set to either 0 or 1 (the default). The reason for this is that the site counter, which the site parameter selects based on, does not reset for each model and therefore site and model are not independent. A good example of where this can be used is with a PDB biological assembly file: setting the modelNo parameter to 0 (use all models), allows a binding site spanning symmetry related proteins marked as different models to be recognized.
