◆ calculateDescriptors()

template<typename T >

void RDMIF::calculateDescriptors	(	RDGeom::UniformRealValueGrid3D &	grd,
		const T &	functor,
		double	thres = `-1.0`
	)

calculates a descriptor at every grid point of MIF

any unary function/functor can be used taking a grid point of type RDKit::Point3D as parameter

Parameters

grd	a UniformRealValueGrid3D
functor	any unary function/functor which takes four doubles as parameters (3 coordinates, 1 threshold)
thres	cuts off atom contributions if distance of interaction higher than threshold, negative threshold: no threshold, defaults to -1.0

◆ constructGrid()

RDKIT_MOLINTERACTIONFIELDS_EXPORT std::unique_ptr< RDGeom::UniformRealValueGrid3D > RDMIF::constructGrid	(	const RDKit::ROMol &	mol,
		int	confId = `-1`,
		double	margin = `5.0`,
		double	spacing = `0.5`
	)

constructs a UniformRealValueGrid3D which fits to the molecule mol

Returns: a pointer to a UniformRealValueGrid which has a spacing of spacing (default: 0.5 Angstrom) and a spatial extent of conformer confId (default: -1) of molecule mol plus a defined margin margin on each side (default: 5.0 Angstrom).

Parameters

mol	Molecule for which the grid is constructed
confId	Id of Conformer which is used
margin	distance from molecule to the grid's wall
spacing	grid's spacing

Returns pointer to a grid

◆ readFromCubeFile()

RDKIT_MOLINTERACTIONFIELDS_EXPORT std::unique_ptr< RDKit::RWMol > RDMIF::readFromCubeFile	(	RDGeom::UniformRealValueGrid3D &	grd,
		const std::string &	filename
	)

reads the contents of the MIF from a file in Gaussian cube format

The Grid grd is modified according to input values If a molecule was associated to the grid on write, a non-null pointer to a molecule is returned with atoms and a conformer, but NO bond information. If there is no atom information in the cube file, a null pointer is returned.

◆ readFromCubeStream()

RDKIT_MOLINTERACTIONFIELDS_EXPORT std::unique_ptr< RDKit::RWMol > RDMIF::readFromCubeStream	(	RDGeom::UniformRealValueGrid3D &	grd,
		std::istream &	inStrm
	)

reads the contents of the MIF from a stream in Gaussian cube format

The Grid grd is modified according to input values If a molecule was associated to the grid on write, a non-null pointer to a molecule is returned with atoms and a conformer, but NO bond information. If there is no atom information in the cube file, a null pointer is returned.

◆ writeToCubeFile()

RDKIT_MOLINTERACTIONFIELDS_EXPORT void RDMIF::writeToCubeFile	(	const RDGeom::UniformRealValueGrid3D &	grd,
		const std::string &	filename,
		const RDKit::ROMol *	mol = `nullptr`,
		int	confid = `-1`
	)

writes the contents of the MIF to a file

The Grid grd is written in Gaussian Cube format A molecule mol and a confId can optionally be provided

◆ writeToCubeStream()

RDKIT_MOLINTERACTIONFIELDS_EXPORT void RDMIF::writeToCubeStream	(	const RDGeom::UniformRealValueGrid3D &	grd,
		std::ostream &	outStrm,
		const RDKit::ROMol *	mol = `nullptr`,
		int	confid = `-1`
	)

writes the contents of the MIF to a stream
