Existing significance-based algorithms consider an organism detected even if a significant number of the microarray probes that match the organism are called absent in a hybridization. Further, they do generate redundant results if the target organisms show high sequence similarity and the microarray probes cannot discriminate all of them.<\/jats:p>\n               <jats:p>Results: We propose a new analysis strategy that considers organism similarities and calls organisms only present if the probes that match the organism but are absent in a hybridization can be explained by random events. In our strategy, we first identify the groups of target organisms that are actually distinguishable by the array. Subsequently, these organism groups are placed in a hierarchical tree such that groups matching only less specific probes are closer to the tree root, and groups that are discriminated only by few probes are close to each other. Finally, we compute for each group a likelihood score that is based on a hypothesis test with the null hypothesis that the group was actually present in the hybridized sample. We have validated our strategy using datasets from two different array types and implemented it as an easy-to-use web application.<\/jats:p>\n               <jats:p>Availability: \u00a0http:\/\/www.fgcz.ethz.ch\/PhyloDetect<\/jats:p>\n               <jats:p>Contact: \u00a0Hubert.Rehrauer@fgcz.uzh.ch<\/jats:p>\n               <jats:p>Supplementary information: Example data is available at<\/jats:p>\n               <jats:p>http:\/\/www.fgcz.ethz.ch\/PhyloDetect<\/jats:p>","DOI":"10.1093\/bioinformatics\/btn269","type":"journal-article","created":{"date-parts":[[2008,8,9]],"date-time":"2008-08-09T13:08:02Z","timestamp":1218287282000},"page":"i83-i89","source":"Crossref","is-referenced-by-count":16,"title":["PhyloDetect: a likelihood-based strategy for detecting microorganisms with diagnostic microarrays"],"prefix":"10.1093","volume":"24","author":[{"given":"Hubert","family":"Rehrauer","sequence":"first","affiliation":[{"name":"1 Functional Genomics Center Zurich, University\/ETH Zurich and 2Institute of Plant Biology, Department of Microbiology, University of Zurich, Zurich, Switzerland"}]},{"given":"Susan","family":"Sch\u00f6nmann","sequence":"additional","affiliation":[{"name":"1 Functional Genomics Center Zurich, University\/ETH Zurich and 2Institute of Plant Biology, Department of Microbiology, University of Zurich, Zurich, Switzerland"}]},{"given":"Leo","family":"Eberl","sequence":"additional","affiliation":[{"name":"1 Functional Genomics Center Zurich, University\/ETH Zurich and 2Institute of Plant Biology, Department of Microbiology, University of Zurich, Zurich, Switzerland"}]},{"given":"Ralph","family":"Schlapbach","sequence":"additional","affiliation":[{"name":"1 Functional Genomics Center Zurich, University\/ETH Zurich and 2Institute of Plant Biology, Department of Microbiology, University of Zurich, Zurich, Switzerland"}]}],"member":"286","published-online":{"date-parts":[[2008,8,9]]},"reference":[{"key":"2023020210495862400_B1","doi-asserted-by":"crossref","first-page":"242","DOI":"10.1016\/j.mimet.2006.11.007","article-title":"Hybridization of genomic DNA to microarrays: a challenge for the analysis of environmental samples","volume":"69","author":"Avarre","year":"2007","journal-title":"J.
