In Genome Research this week, Michael Brudno and his colleagues at the University of Toronto describe a method to detect copy-number variation via mated short reads, wherein "matepairs mapping discordantly to the reference serve to indicate the presence of variation." CNVer — the team's algorithm — combines this information and allows researchers to "mitigate the sequencing biases that cause uneven local coverage and accurately predict CNVs." Brudno et al.
