PureCN (version 1.0.4)

Estimating tumor purity, ploidy, LOH, and SNV status using hybrid capture NGS data

Description

This package estimates tumor purity, copy number, loss of heterozygosity (LOH), and status of single nucleotide variants (SNVs). PureCN is designed for hybrid capture sequencing data, integrates well with standard somatic variant detection pipelines, and has support for tumor samples without matching normal samples.
