POPTREEW: Web version of POPTREE for constructing population trees from allele frequency data and computing some other quantities

POPTREE software, including the command line (POPTREE) and the Windows (POPTREE2) versions, is available to perform evolutionary analyses of allele frequency data, computing distance measures for constructing population trees and average heterozygosity (H) (measure of genetic diversity within populations) and GST (measure of genetic differentiation among subdivided populations). We have now developed a web version POPTREEW (http://www.med. kagawa-u.ac.jp/~genomelb/takezaki/poptreew/) to provide cross-platform access to all POPTREE functions including interactive tree editing. Furthermore, new POPTREE software (POPTREE, POPTREE2, and POPTREEW) computes standardized GST and Jost’s D, which may be appropriate for data with high variability, and accepts genotype data in GENEPOP format as an input.
