segmentSamplesUsingPopInformation {CNVrd2} | R Documentation |
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. Then, the function adjusts segmentation scores for multiple populations using a linear regression model.
segmentSamplesUsingPopInformation(Object, ...)
Object |
An object of class CNVrd2. |
... |
Optional arguments. |
segmentationScores |
All adjusted results of the segmentation process. |
segmentationScoresFromSinglePops |
Segmentation scores of single populations. |
segmentResults |
Un-adjusted segmentation scores |
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). |
