One of the most important somatic aberrations, copy number variations (CNVs) in tumor genomes is believed to have a high probability of harboring oncotargets. Detection of somatic CNVs is an essential part of cancer genome sequencing analysis, but the accuracy is usually limited due to various factors. A post-processing procedure including manual review and refinement of CNV segments is sorely needed in practice to achieve better accuracy. cnvCurator is a tool with functions designed to facilitate the process of interactively visualizing and refining somatic CNV calling results.
