SUMMARY: DnaSP is a software package for the analysis of DNA polymorphism data. Present version introduces several new modules and features which, among other options allow: (1) handling big data sets (approximately 5 Mb per sequence); (2) conducting a large number of coalescent-based tests by Monte Carlo computer simulations; (3) extensive analyses of the genetic differentiation and gene flow among populations; (4) analysing the evolutionary pattern of preferred and unpreferred codons; (5) generating graphical outputs for an easy visualization of results. AVAILABILITY: The software package, including complete documentation and examples, is freely available to academic users from: http://www.ub.es/dnasp

UNLABELLED: DnaSP is a Windows integrated software package for the analysis of the DNA polymorphism from nucleotide sequence data. DnaSP version 3 incorporates several methods for estimating the amount and pattern of DNA polymorphism and divergence, and for conducting neutrality tests. AVAILABILITY: For academic uses, DnaSP is available free of charge from: http://www.bio.ub.es/julio/DnaSP.html CONTACT: [email protected]

DnaSP, DNA sequence polymorphism, is an interactive computer program for the analysis of DNA polymorphism from nucleotide sequence data. The program, addressed to molecular population geneticists, calculates several measures of DNA sequence variation within and between populations, linkage disequilibrium parameters and Tajima's D statistic. The program, which is written in Visual Basic v. 3.0 and runs on an IBM-compatible PC under Windows, can handle a large number of sequences of up to thousands of nucleotides each.
