Phyloscan Version 2 web server is available. Lee Newberg, Wadsworth Center 24 March 2009 Carmack et al. (Algorithms for Molecular Biology 2007, doi:10.1186/1748-7188-2-1) includes a web link to the Phyloscan Version 1 web server, which analyzes genomic sequence data from E. coli and related proteobacteria. There is now a Phyloscan Version 2 web server that permits analysis of user-supplied sequence data. The new web server can be found at http://bayesweb.wadsworth.org/cgi-bin/phyloscanV2.pl.
