Current approaches are either focused on sensitivity estimation and thereby disregard specificity or are based on read simulations. Although continuously improving, read simulations are still prone to introduce a bias into the mapping error quantitation and cannot capture all characteristics of an individual dataset.<\/jats:p>\n               <jats:p>Results: We introduce ARDEN (artificial reference driven estimation of false positives in next-generation sequencing data), a novel benchmark method that estimates error rates of read mappers based on real experimental reads, using an additionally generated artificial reference genome. It allows a dataset-specific computation of error rates and the construction of a receiver operating characteristic curve. Thereby, it can be used for optimization of parameters for read mappers, selection of read mappers for a specific problem or for filtering alignments based on quality estimation. The use of ARDEN is demonstrated in a general read mapper comparison, a parameter optimization for one read mapper and an application example in single-nucleotide polymorphism discovery with a significant reduction in the number of false positive identifications.<\/jats:p>\n               <jats:p>Availability: The ARDEN source code is freely available at http:\/\/sourceforge.net\/projects\/arden\/.<\/jats:p>\n               <jats:p>Contact: \u00a0renardb@rki.de<\/jats:p>\n               <jats:p>Supplementary information: \u00a0Supplementary data are available at Bioinformatics online.<\/jats:p>","DOI":"10.1093\/bioinformatics\/btt255","type":"journal-article","created":{"date-parts":[[2013,5,18]],"date-time":"2013-05-18T04:22:56Z","timestamp":1368850976000},"page":"9-16","source":"Crossref","is-referenced-by-count":15,"title":["Specificity control for read alignments using an artificial reference genome-guided false discovery rate"],"prefix":"10.1093","volume":"30","author":[{"given":"Sven H.","family":"Giese","sequence":"first","affiliation":[{"name":"Research Group Bioinformatics (NG4), Robert Koch-Institut, Nordufer 20, 13353 Berlin, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Franziska","family":"Zickmann","sequence":"additional","affiliation":[{"name":"Research Group Bioinformatics (NG4), Robert Koch-Institut, Nordufer 20, 13353 Berlin, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bernhard Y.","family":"Renard","sequence":"additional","affiliation":[{"name":"Research Group Bioinformatics (NG4), Robert Koch-Institut, Nordufer 20, 13353 Berlin, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2013,5,17]]},"reference":[{"key":"2023012710380890200_btt255-B1","doi-asserted-by":"crossref","first-page":"e72","DOI":"10.1093\/nar\/gks001","article-title":"Summarizing and correcting the GC content bias in high-throughput sequencing","volume":"40","author":"Benjamini","year":"2012","journal-title":"Nucleic Acids Res."},{"key":"2023012710380890200_btt255-B2","doi-asserted-by":"crossref","first-page":"R109","DOI":"10.1186\/gb-2011-12-10-r109","article-title":"Variation in global codon usage bias among prokaryotic organisms is associated with their lifestyles","volume":"12","author":"Botzman","year":"2011","journal-title":"Genome Biol."},{"key":"2023012710380890200_btt255-B3","doi-asserted-by":"crossref","first-page":"47","DOI":"10.1021\/pr700747q","article-title":"False discovery rates and related statistical concepts in mass spectrometry-based proteomics","volume":"7","author":"Choi","year":"2008","journal-title":"J.
