Class BiologicalAssemblyTransformation

java.lang.Object

org.biojava.nbio.structure.quaternary.BiologicalAssemblyTransformation

All Implemented Interfaces:

Serializable, Cloneable

public class BiologicalAssemblyTransformation
extends Object
implements Cloneable, Serializable

The transformation needed for generation of biological assemblies from the contents of a PDB/mmCIF file. It contains both the actual transformation (rotation+translation) and the chain identifier to which it should be applied.

Constructor Detail

BiologicalAssemblyTransformation

public BiologicalAssemblyTransformation()

Default Constructor

BiologicalAssemblyTransformation

public BiologicalAssemblyTransformation(BiologicalAssemblyTransformation src)

Copy Constructor

Parameters:

src -

Method Detail

setId

public void setId(String id)

Sets the identifier for this biological assembly transformation. This is usually the model number used in the biological assembly files.

Parameters:

id -

getId

public String getId()

Returns the identifier for this biological assembly transformation.

Returns:

biological assembly transformation identifier

setChainId

public void setChainId(String chainId)

Sets the chain identifier (asym id) that this transformation should be applied to.

Parameters:

chainId -

getChainId

public String getChainId()

Returns the chain identifier (asym id) that this transformation should be applied to.

Returns:

chain identifier

setTransformationMatrix

public void setTransformationMatrix(javax.vecmath.Matrix4d transformation)

Sets the transformation using a 4x4 transformation matrix

Parameters:

transformation -

getTransformationMatrix

public javax.vecmath.Matrix4d getTransformationMatrix()

Return the transformation (both rotational and translational component) as a 4x4 transformation matrix. The transformation is in orthonormal (cartesian coordinates). If required to be converted to crystal coordinates then use CrystalCell.transfToCrystal(Matrix4d) Note that this is a reference to the variable, thus it remains linked to this object's transformation field. The user must deep copy it if need changing it.

Returns:

4x4 transformation matrix

setRotationMatrix

public void setRotationMatrix(double[][] m)

setTranslation

public void setTranslation(double[] t)

transformPoint

public void transformPoint(double[] point)

Applies the transformation to given point.

combine

public static BiologicalAssemblyTransformation combine(BiologicalAssemblyTransformation matrix1,
                                                       BiologicalAssemblyTransformation matrix2)

Returns the combination (product) of two biological assembly transformations.

Parameters:

matrix1 -

matrix2 -

Returns:

combined transformation

isIdentity

public boolean isIdentity()

Tells whether this transformation is in identity.

Returns:
