SUMMARY: VisRD, a program for visual recombination detection in a sequence alignment is presented. VisRD is written in Java and is designed to complement the multi-purpose phylogenetic software package SplitsTree4. AVAILABILITY: The software is freely available from http://www.lcb.uu.se/~vmoulton/software/visrd/
A versatile visual approach for detecting recombination and identifying recombination breakpoints within a sequence alignment is presented. The method is based on two novel diagrams - the highway plot and the occupancy plot - that graphically portray phylogenetic inhomogeneity along an alignment, and can be viewed as a synthesis of two widely used but unrelated methods: bootscanning and quartet-mapping. To illustrate the method, simulated data and HIV-1 and influenza A datasets are investigated.
