Raw contiguous regions from VarScan 2 are processed by circular binary segmentation (CBS) and a subsequent merging procedure that joins adjacent segments yields a set of somatic copy number Europe PMC is an archive of life sciences journal literature. Only positions that are present in both files, and meet the minimum coverage in both files, will be compared. In some SNPs, the genotype for normal sample is 1/1 and the alt read count in the normal is 0. It can detect SNPs, indels, and copy number variations in both somatic and germline samples.
