Association strength is determined by proteomic distance for PPT and gene-distribution distance for O-HARP. For instance, phage bIL170 has a darker grey than bIL67 in the sk1-like group for the alphabet letter "P" because it has a closer proteomic distance to phage sk1. Phage 933W has a light grey for "O" because its gene distribution (computed by O-HARP) is not as close to phage as some other phages such as HK97 and P22. Abbreviation: Φ – Bacteriophage.<p><b>Copyright information:</b></p><p>Taken from "Genome classification by gene distribution: An overlapping subspace clustering approach"</p><p>http://www.biomedcentral.com/1471-2148/8/116</p><p>BMC Evolutionary Biology 2008;8():116-116.</p><p>Published online 23 Apr 2008</p><p>PMCID:PMC2383906.</p><p></p
