HMMcopy example dataset
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.
