PoPoolation2: identifying differentiation between populations using sequencing of pooled DNA samples (Pool-Seq)

SUMMARY: Sequencing pooled DNA samples (Pool-Seq) is the most cost-effective approach for the genome-wide comparison of population samples. Here, we introduce PoPoolation2, the first software tool specifically designed for the comparison of populations with Pool-Seq data. PoPoolation2 implements a range of commonly used measures of differentiation (F(ST), Fisher's exact test and Cochran-Mantel-Haenszel test) that can be applied on different scales (windows, genes, exons, SNPs). The result may be visualized with the widely used Integrated Genomics Viewer. AVAILABILITY AND IMPLEMENTATION: PoPoolation2 is implemented in Perl and R.
