CMS incorporates the scores from five different tests for selection. These include three haplotype-based tests (iHS, XP-EHH and ΔiHH), one for differentiated alleles (Fst), and a fifth for derived allele frequency (ΔDAF). iHS and XP-EHH are calculated as described in refs. and , respectively. ΔiHH is a modification of the iHS … Se mer CMS is used to localize the signal of selection within a given region of the genome and identify the variants that are most likely to be causal.
