TiMEx explicitly accounts for the temporal interplay between the waiting times to alterations and the observation time. In simulation studies, we show that our model outperforms previous methods for detecting mutual exclusivity. On large-scale biological datasets, TiMEx identifies gene groups with strong functional biological relevance, while also proposing new candidates for biological validation. TiMEx possesses several advantages over previous methods, including a novel generative probabilistic model of tumorigenesis, direct estimation of the probability of mutual exclusivity interaction, computational efficiency and high sensitivity in detecting gene groups involving low-frequency alterations.<\/jats:p>\n               <jats:p>Availability and implementation: TiMEx is available as a Bioconductor R package at www.bsse.ethz.ch\/cbg\/software\/TiMEx .<\/jats:p>\n               <jats:p>Contact: \u00a0niko.beerenwinkel@bsse.ethz.ch<\/jats:p>\n               <jats:p>Supplementary information : Supplementary data are available at Bioinformatics online.<\/jats:p>","DOI":"10.1093\/bioinformatics\/btv400","type":"journal-article","created":{"date-parts":[[2015,7,11]],"date-time":"2015-07-11T00:54:43Z","timestamp":1436576083000},"page":"968-975","source":"Crossref","is-referenced-by-count":53,"title":["TiMEx: a waiting time model for mutually exclusive cancer alterations"],"prefix":"10.1093","volume":"32","author":[{"given":"Simona","family":"Constantinescu","sequence":"first","affiliation":[{"name":"1 Department of Biosystems Science and Engineering, ETH Z\u00fcrich,"},{"name":"2 Swiss Institute of Bioinformatics, Basel 4058, Switzerland and"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ewa","family":"Szczurek","sequence":"additional","affiliation":[{"name":"1 Department of Biosystems Science and Engineering, ETH Z\u00fcrich,"},{"name":"2 Swiss Institute of Bioinformatics, Basel 4058, Switzerland and"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pejman","family":"Mohammadi","sequence":"additional","affiliation":[{"name":"1 Department of Biosystems Science and Engineering, ETH Z\u00fcrich,"},{"name":"2 Swiss Institute of Bioinformatics, Basel 4058, Switzerland and"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J\u00f6rg","family":"Rahnenf\u00fchrer","sequence":"additional","affiliation":[{"name":"3 Faculty of Statistics, Technische Universit\u00e4t Dortmund, Dortmund 44221, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Niko","family":"Beerenwinkel","sequence":"additional","affiliation":[{"name":"1 Department of Biosystems Science and Engineering, ETH Z\u00fcrich,"},{"name":"2 Swiss Institute of Bioinformatics, Basel 4058, Switzerland and"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2015,7,9]]},"reference":[{"key":"2023020112010885900_btv400-B1","doi-asserted-by":"crossref","first-page":"575","DOI":"10.1145\/362342.362367","article-title":"Algorithm 457: finding all cliques of an undirected graph","volume":"16","author":"Bron","year":"1973","journal-title":"Commun.
