◆ canonicalizeConformer()

RDKIT_MOLTRANSFORMS_EXPORT void MolTransforms::canonicalizeConformer	(	RDKit::Conformer &	conf,
		const RDGeom::Point3D *	center = `nullptr`,
		bool	normalizeCovar = `false`,
		bool	ignoreHs = `true`
	)

Canonicalize the orientation of a conformer so that its principal axes around the specified center point coincide with the x, y, z axes

Parameters

conf	The conformer of interest
center	Optional center point about which the principal axes are computed if not specified the centroid of the conformer will be used
normalizeCovar	Optionally normalize the covariance matrix by the number of atoms
ignoreHs	If true, ignore hydrogen atoms

◆ canonicalizeMol()

RDKIT_MOLTRANSFORMS_EXPORT void MolTransforms::canonicalizeMol	(	RDKit::ROMol &	mol,
		bool	normalizeCovar = `false`,
		bool	ignoreHs = `true`
	)

Canonicalize all the conformations in a molecule.

Parameters

mol	the molecule of interest
normalizeCovar	Optionally normalize the covariance matrix by the number of atoms
ignoreHs	If true, ignore hydrogens

◆ computeCanonicalTransform()

RDKIT_MOLTRANSFORMS_EXPORT RDGeom::Transform3D * MolTransforms::computeCanonicalTransform	(	const RDKit::Conformer &	conf,
		const RDGeom::Point3D *	center = `nullptr`,
		bool	normalizeCovar = `false`,
		bool	ignoreHs = `true`
	)

Compute the transformation required to orient the conformation along the principal axes about the center; i.e. center is made to coincide with the origin, the largest principal axis with the x-axis, the next largest with the y-axis and the smallest with the z-axis

If center is not specified the centroid of the conformer will be used

Parameters

conf	Conformer of interest
center	Center to be used for canonicalization, defaults to the centroid of the conformation
normalizeCovar	Normalize the covariance matrix with the number of atoms
ignoreHs	Optionally ignore hydrogens

◆ computeCentroid()

RDKIT_MOLTRANSFORMS_EXPORT RDGeom::Point3D MolTransforms::computeCentroid	(	const RDKit::Conformer &	conf,

	)

Compute the centroid of a conformer.

This is simple the average of the heavy atom locations in the conformer, not attention is paid to hydrogens or the differences in atomic radii

Parameters

conf	Conformer of interest
ignoreHs	If true, ignore hydrogen atoms
weights	If present, used to weigh the atomic coordinates
