HMMcopy-dataset: HMMcopy example dataset

Description Usage Format References

Description

A set of data of chromosome 6 of matched tumour normal pair. The dataset that is described here belongs to a female triple-negative breast cancer patient from the dataset published in Shah2012,Ha2012. This genome library was sequenced on the ABI/Life SOLiD platform, generating hybrid lengths of 25bp and 50bp paired-end reads. The reads were aligned using BioScope https://products.appliedbiosystems.com/ where reads mapped to multiple sites were ignored.

tumour_reads

The number of short reads in fixed width windows across the chromosome, generated with wigsToRangedData from WIG files

tumour_copy

Tumour copy number profile generated by correcting ‘tumour_reads’ with correctReadcount

normal_copy

Normal copy number profile generated via correctReadcount

tumour_param

Parameters for segmenting ‘tumour_copy’ in HMMsegment

tumour_segments

Segmented output of ‘tumour_copy’ HMMsegment

using ‘tumour_param’

Usage

Format

‘tumour_reads’, ‘tumour_copy’, and ‘normal_copy’ are RangedData objects.

‘tumour_param’ is a numeric matrix.

‘tumour_segments’ is a list.
