segmentSamples {CNVrd2} | R Documentation

## Implement the segmentation process

### Description

Segment read-count windows into region having similar signal values by using the DNAcopy package (Venkatraman and Olshen, 2007) and refine this process to obtain segmentation scores at genes.

### Usage

    segmentSamples(Object, ...)

### Arguments

`Object` | An object of class CNVrd2.
`...` | Optional arguments.

### Value

`segmentResults` | All results of the segmentation process.
`segmentationScores` | Segmentation scores of the gene(s) being measured.
`observedReadCountRatios` | Observed read-count ratios of genes. This value is a matrix of observed read-count ratios at genes if (only inputBamFile = TRUE).
`stdCntMatrix` | Matrix of read counts (standardized).
