Description Installation and updates To get started How to cite License Author(s) References

Description

Segmentation of allele-specific DNA copy number data and detection of regions with abnormal copy number within each parental chromosome. Both tumor-normal paired and tumor-only analyses are supported..

This package should be considered to be in an alpha or beta phase. You should expect the API to be changing over time.

Installation and updates

To install this package, use install.packages("PSCBS").

To get started

To get started, see:

  1. Vignettes 'Parent-specific copy-number segmentation using Paired PSCBS' and 'Total copy-number segmentation using CBS'.

  2. segmentByCBS() - segments total copy-numbers, or any other unimodal genomic signals, using the CBS method [3,4].

  3. segmentByPairedPSCBS() - segments allele-specific tumor signal from a tumor with a matched normal using the Paired PSCBS method [1,2].

  4. segmentByNonPairedPSCBS() - segments allele-specific tumor signal from a tumor without a matched normal using the Non-Paired PSCBS method adopted from [1,2].

How to cite

Please use [1] and [2] to cite when using Paired PSCBS, and [3] and [4] when using CBS. When using Non-Paired PSCBS, please cite [1] and [2] as well.
