Class AlignRigidEasy

java.lang.Object
  chemaxon.marvin.alignment.AlignRigidEasy

All Implemented Interfaces:

chemaxon.license.Licensable

public class AlignRigidEasy
extends java.lang.Object
implements chemaxon.license.Licensable

Aligns pairs of molecules by translating and rotating one of them and leave the one called the reference molecule intact. Example usage

           AlignRigidEasy easy = new AlignRigidEasy();
           easy.setReference(m1);
           easy.setRotatable(m2);

           int[][] easyMap = new int[number of pairs][2];
           for (int i = 0; i < easyMap.length; i++) {
               easyMap[i][0] = atom index from m1;
               easyMap[i][1] = atom index from m2;
           }
           easy.align(easyMap);
           double rmsd = easy.rmsd();

Method Summary

void	align() does a simple one-to-one atom mappin and aligns.
void	align(int[][] index) Rigid alignment on the user defined atom index
static double[]	convert(double[][] c)
Molecule	getReferenceAndRotatedFused() before getRotatedMolecule the align() method must be called

Molecule	getRotatedMolecule() before getRotatedMolecule the align() method must be called
boolean	isLicensed()
double	rmsd() calculates the rmsd value
void	setLicenseEnvironment(java.lang.String env)
void	setReference(double[][] c) sets the coordinates of the reference molecule directly If this used the getReferenceAndRotatedFused() cannot be applied
void	setReference(Molecule m) sets the reference molecule which remains intact
void	setRotatable(double[][] c) sets the coordinates of the rotatable molecule directly If this used the getReferenceAndRotatedFused() and getRotatedMolecule() cannot be applied
void	setRotatable(Molecule m) sets the molecule to translate and rotate during the alignment

AlignRigidEasy

public AlignRigidEasy()

Method Detail

isLicensed

public boolean isLicensed()

Specified by:

isLicensed in interface chemaxon.license.Licensable

setLicenseEnvironment

public void setLicenseEnvironment(java.lang.String env)

Specified by:

setLicenseEnvironment in interface chemaxon.license.Licensable

setReference

public void setReference(Molecule m)

sets the reference molecule which remains intact

Parameters:

m -

setRotatable

public void setRotatable(Molecule m)

sets the molecule to translate and rotate during the alignment

Parameters:

m - molecule to translate and rotate

convert

public static double[] convert(double[][] c)

setReference

public void setReference(double[][] c)

sets the coordinates of the reference molecule directly If this used the getReferenceAndRotatedFused() cannot be applied

Parameters:

c - double[number of atoms][3:x,y,z] format

setRotatable

public void setRotatable(double[][] c)

sets the coordinates of the rotatable molecule directly If this used the getReferenceAndRotatedFused() and getRotatedMolecule() cannot be applied

Parameters:

c - double[number of atoms][3:x,y,z] format

getRotatedCoordinates

public double[][] getRotatedCoordinates()

before getRotatedCoordinates the align() method must be called

Returns:

the rotated coordinates in double[number of atoms][3:x,y,z] format

getRotatedMolecule

public Molecule getRotatedMolecule()

before getRotatedMolecule the align() method must be called

Returns:

the rotated molecule

getReferenceAndRotatedFused

public Molecule getReferenceAndRotatedFused()

before getRotatedMolecule the align() method must be called

Returns:

the rotated molecule

rmsd

public double rmsd()

calculates the rmsd value

Returns:

the rmsd value

align

public void align()

does a simple one-to-one atom mappin and aligns. The molecules must have the same atom count.

Throws:

chemaxon.license.LicenseException - if no valid LicenseHandler.ALIGNMENT license was found.

align

public void align(int[][] index)

Rigid alignment on the user defined atom index

Parameters:

index - in format int[number of pairs][reference atom index, atom to rotate index]

Throws:

chemaxon.license.LicenseException - if no valid LicenseHandler.ALIGNMENT license was found.
