A number of general purpose matrices have been proposed (e.g. JTT, WAG, LG) since the seminal work of Margaret Dayhoff and co-workers. However, it has been shown that matrices specific to certain protein groups (e.g. mitochondrial) or life domains (e.g. viruses) differ significantly from general average matrices, and thus perform better when applied to the data to which they are dedicated. This Web server implements the maximum-likelihood estimation procedure that was used to estimate LG, and provides a number of tools and facilities. Users upload a set of multiple protein alignments from their domain of interest and receive the resulting matrix by email, along with statistics and comparisons with other matrices. A non-parametric bootstrap is performed optionally to assess the variability of replacement rate estimates. Maximum-likelihood trees, inferred using the estimated rate matrix, are also computed optionally for each input alignment. Finely tuned procedures and up-to-date ML software (PhyML 3.0, XRATE) are combined to perform all these heavy calculations on our clusters.<\/jats:p>\n               <jats:p>Availability: \u00a0http:\/\/www.atgc-montpellier.fr\/ReplacementMatrix\/<\/jats:p>\n               <jats:p>Contact: \u00a0olivier.gascuel@lirmm.fr<\/jats:p>\n               <jats:p>Supplementary information: \u00a0Supplementary data are available at http:\/\/www.atgc-montpellier.fr\/ReplacementMatrix\/<\/jats:p>","DOI":"10.1093\/bioinformatics\/btr435","type":"journal-article","created":{"date-parts":[[2011,7,27]],"date-time":"2011-07-27T00:55:56Z","timestamp":1311728156000},"page":"2758-2760","source":"Crossref","is-referenced-by-count":16,"title":["ReplacementMatrix: a web server for maximum-likelihood estimation of amino acid replacement rate matrices"],"prefix":"10.1093","volume":"27","author":[{"given":"Cuong Cao","family":"Dang","sequence":"first","affiliation":[{"name":"1 College of Technology and Information Technology Institute, Vietnam National University, Hanoi, Vietnam, 2M\u00e9thodes et algorithmes pour la Bioinformatique, LIRMM, CNRS \u2013 Universit\u00e9 Montpellier 2, Montpellier, France and 3Wellcome Trust Sanger Institute, Genome Campus, Hinxton, Cambridge CB10 1SA, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Vincent","family":"Lefort","sequence":"additional","affiliation":[{"name":"1 College of Technology and Information Technology Institute, Vietnam National University, Hanoi, Vietnam, 2M\u00e9thodes et algorithmes pour la Bioinformatique, LIRMM, CNRS \u2013 Universit\u00e9 Montpellier 2, Montpellier, France and 3Wellcome Trust Sanger Institute, Genome Campus, Hinxton, Cambridge CB10 1SA, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Vinh Sy","family":"Le","sequence":"additional","affiliation":[{"name":"1 College of Technology and Information Technology Institute, Vietnam National University, Hanoi, Vietnam, 2M\u00e9thodes et algorithmes pour la Bioinformatique, LIRMM, CNRS \u2013 Universit\u00e9 Montpellier 2, Montpellier, France and 3Wellcome Trust Sanger Institute, Genome Campus, Hinxton, Cambridge CB10 1SA, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Quang Si","family":"Le","sequence":"additional","affiliation":[{"name":"1 College of Technology and Information Technology Institute, Vietnam National University, Hanoi, Vietnam, 2M\u00e9thodes et algorithmes pour la Bioinformatique, LIRMM, CNRS \u2013 Universit\u00e9 Montpellier 2, Montpellier, France and 3Wellcome Trust Sanger Institute, Genome Campus, Hinxton, Cambridge CB10 1SA, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Olivier","family":"Gascuel","sequence":"additional","affiliation":[{"name":"1 College of Technology and Information Technology Institute, Vietnam National University, Hanoi, Vietnam, 2M\u00e9thodes et algorithmes pour la Bioinformatique, LIRMM, CNRS \u2013 Universit\u00e9 Montpellier 2, Montpellier, France and 3Wellcome Trust Sanger Institute, Genome Campus, Hinxton, Cambridge CB10 1SA, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2011,7,26]]},"reference":[{"key":"2023012512010438400_B1","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1093\/molbev\/msl136","article-title":"MtArt: a new model of amino acid replacement for Arthropoda","volume":"24","author":"Abascal","year":"2007","journal-title":"Mol.
