Member Function Documentation

◆ setSmoothingFactor()

void CDPL::Descr::MoleculeRDFDescriptorCalculator::setSmoothingFactor ( double factor )

Allows to specify the smoothing factor used in the calculation of atom pair RDF contributions.

Parameters

factor The smoothing factor.

Note: The default value of the smoothing factor is 1.0.

◆ getSmoothingFactor()

double CDPL::Descr::MoleculeRDFDescriptorCalculator::getSmoothingFactor ( ) const

Returns the smoothing factor used in the calculation of atom pair RDF contributions.

Returns: The applied smoothing factor.

◆ setScalingFactor()

void CDPL::Descr::MoleculeRDFDescriptorCalculator::setScalingFactor ( double factor )

Allows to specify the scaling factor for the RDF code elements.

Parameters

factor The scaling factor.

Note: The default scaling factor is 1.0.

◆ getScalingFactor()

double CDPL::Descr::MoleculeRDFDescriptorCalculator::getScalingFactor ( ) const

Returns the scaling factor applied to the RDF code elements.

Returns: The applied scaling factor.

◆ setStartRadius()

void CDPL::Descr::MoleculeRDFDescriptorCalculator::setStartRadius ( double start_radius )

Sets the starting value of the radius.

Parameters

start_radius The starting value of the radius.

Note: The default starting radius is 0.0Å.

◆ getStartRadius()

double CDPL::Descr::MoleculeRDFDescriptorCalculator::getStartRadius ( ) const

Returns the starting value of the radius.

Returns: The current radius starting value.

◆ setRadiusIncrement()

void CDPL::Descr::MoleculeRDFDescriptorCalculator::setRadiusIncrement ( double radius_inc )

Sets the radius step size between successive RDF code elements.

Parameters

radius_inc The radius step size.

Note: The default radius step size is 0.1Å.

◆ getRadiusIncrement()

double CDPL::Descr::MoleculeRDFDescriptorCalculator::getRadiusIncrement ( ) const

Returns the radius step size between successive RDF code elements.

Returns: The applied radius step size.

◆ setNumSteps()

void CDPL::Descr::MoleculeRDFDescriptorCalculator::setNumSteps ( std::size_t num_steps )

Sets the number of desired radius incrementation steps.

The number of performed radius incrementation steps defines the size of the calculated RDF code vector which is equal to the number of steps plus 1.

Parameters

num_steps The number of radius incrementation steps.

Note: The default number of steps is 99.

◆ getNumSteps()

std::size_t CDPL::Descr::MoleculeRDFDescriptorCalculator::getNumSteps ( ) const

Returns the number of performed radius incrementation steps.

Returns: The number of performed radius incrementation steps.

◆ setAtom3DCoordinatesFunction()

void CDPL::Descr::MoleculeRDFDescriptorCalculator::setAtom3DCoordinatesFunction ( const Atom3DCoordinatesFunction & func )

Allows to specify the atom coordinates function.

Parameters

func	A Atom3DCoordinatesFunction instance that wraps the target function.

Note: The coordinates function must be specified before calling calculate(), otherwise a zero distance for each atom pair will be used for the calculation.

◆ setAtomPairWeightFunction()

void CDPL::Descr::MoleculeRDFDescriptorCalculator::setAtomPairWeightFunction ( const AtomPairWeightFunction & func )

Allows to specify a custom atom pair weight function.

Parameters

func	A AtomPairWeightFunction instance that wraps the target function.

◆ enableDistanceToIntervalCenterRounding()

void CDPL::Descr::MoleculeRDFDescriptorCalculator::enableDistanceToIntervalCenterRounding ( bool enable )

Allows to specify whether atom pair distances should be rounded to the nearest radius interval center.

Parameters

enable true if pair distances should be rounded, and false otherwise.

Note: The default setting is not to round the atom pair distances.

◆ distanceToIntervalsCenterRoundingEnabled()

bool CDPL::Descr::MoleculeRDFDescriptorCalculator::distanceToIntervalsCenterRoundingEnabled ( ) const

Tells whether atom pair distances get rounded to the nearest radius interval centers.

Returns: true if pair distances get rounded, and false otherwise.

◆ calculate()

void CDPL::Descr::MoleculeRDFDescriptorCalculator::calculate	(	const Chem::AtomContainer &	cntnr,
		Math::DVector &	descr
	)
