public class ExpressionDataDoubleMatrix
extends AbstractMultiAssayExpressionDataMatrix<Double>
implements BulkExpressionDataPrimitiveDoubleMatrix

A data structure that holds a reference to the data for a given expression experiment. The data can be queried by row or column, returning data for a specific DesignElement or data for a specific BioAssay. This class is not database aware so the vectors provided must already be 'thawed'.

Constructor Details

ExpressionDataDoubleMatrix

public ExpressionDataDoubleMatrix()

To comply with bean specifications. Not to be instantiated.

ExpressionDataDoubleMatrix

public ExpressionDataDoubleMatrix(Collection<? extends BulkExpressionDataVector> vectors)

ExpressionDataDoubleMatrix

public ExpressionDataDoubleMatrix(ExpressionExperiment ee,
 Collection<? extends BulkExpressionDataVector> vectors)

ExpressionDataDoubleMatrix

public ExpressionDataDoubleMatrix(Collection<? extends BulkExpressionDataVector> dataVectors,
 Collection<QuantitationType> quantitationTypes)

ExpressionDataDoubleMatrix

public ExpressionDataDoubleMatrix(Collection<? extends BulkExpressionDataVector> dataVectors,
 QuantitationType quantitationType)

ExpressionDataDoubleMatrix

public ExpressionDataDoubleMatrix(ExpressionDataDoubleMatrix sourceMatrix,
 DoubleMatrix<CompositeSequence,BioMaterial> dataMatrix,
 Collection<QuantitationType> quantitationTypes)

Create a data matrix like sourceMatrix but use the values and quantitations from dataMatrix.

Note: The rows can be different from the original matrix, but the columns must be the same.

Parameters:

sourceMatrix - source matrix from which most of the meta-data will be imported

dataMatrix - data matrix to use

quantitationTypes - quantitation types used by the dataMatrix

ExpressionDataDoubleMatrix

public ExpressionDataDoubleMatrix(ExpressionDataDoubleMatrix dmatrix,
 DoubleMatrix<CompositeSequence,BioMaterial> copiedMatrix)

ExpressionDataDoubleMatrix

public ExpressionDataDoubleMatrix(ExpressionExperiment ee,
 QuantitationType qt,
 DoubleMatrix<CompositeSequence,BioMaterial> matrix)

Create a matrix given a 'raw' matrix that uses the same samples as the experiment. Only simple situations are supported (one platform, not subsetting the dataset).

Parameters:

ee - to be associated with this

qt - to be associated with this

matrix - with valid row and column elements, and the data

ExpressionDataDoubleMatrix

public ExpressionDataDoubleMatrix(ExpressionDataDoubleMatrix sourceMatrix,
 List<BioMaterial> columnsToUse,
 BioAssayDimension reorderedDim)

Create a matrix based on another one's selected columns. The results will be somewhat butchered - only a single BioAssayDimension and the ranks will be copied over (not recomputed based on the selected columns).

Parameters:

sourceMatrix - matrix

columnsToUse - columns

reorderedDim - the reordered bioAssayDimension.
