CBS: The CBS class

Description Usage Arguments Fields and Methods Difference to DNAcopy object See also Author(s)


A CBS object holds results from the Circular Binary Segmentation (CBS) method for one sample for one or more chromosomes.

Package: PSCBS
Class CBS


Directly known subclasses:

public abstract static class CBS
extends AbstractCBS





Arguments passed to the constructor of AbstractCBS.

Fields and Methods

Difference to DNAcopy object

A CBS object is similar to DNAcopy objects with the major difference that a CBS object holds only one sample, whereas a DNAcopy object can hold more than one sample.
