RNA structure prediction tools such as PPfold or RNAalifold use an aligned set of sequences in predictions. Obtaining a multiple alignment from a set of sequences is quite a challenging problem itself, and the quality of the alignment can affect the quality of a prediction. By implementing RNA secondary structure prediction in a statistical alignment framework, and predicting structures from multiple alignment samples instead of a single fixed alignment, it may be possible to improve predictions.<\/jats:p>\n               <jats:p>Results: We have extended the program StatAlign to make use of RNA-specific features, which include RNA secondary structure prediction from multiple alignments using either a thermodynamic approach (RNAalifold) or a Stochastic Context-Free Grammars (SCFGs) approach (PPfold). We also provide the user with scores relating to the quality of a secondary structure prediction, such as information entropy values for the combined space of secondary structures and sampled alignments, and a reliability score that predicts the expected number of correctly predicted base pairs. Finally, we have created RNA secondary structure visualization plugins and automated the process of setting up Markov Chain Monte Carlo runs for RNA alignments in StatAlign.<\/jats:p>\n               <jats:p>Availability and implementation: The software is available from http:\/\/statalign.github.com\/statalign\/.<\/jats:p>\n               <jats:p>Contact: novak@stats.ox.ac.uk<\/jats:p>\n               <jats:p>Supplementary information: Supplementary data are available at Bioinformatics online.<\/jats:p>","DOI":"10.1093\/bioinformatics\/btt025","type":"journal-article","created":{"date-parts":[[2013,1,19]],"date-time":"2013-01-19T04:00:52Z","timestamp":1358568052000},"page":"654-655","source":"Crossref","is-referenced-by-count":14,"title":["StatAlign 2.0: combining statistical alignment with RNA secondary structure prediction"],"prefix":"10.1093","volume":"29","author":[{"given":"Preeti","family":"Arunapuram","sequence":"first","affiliation":[{"name":"1 Department of Computer Science, University of North Carolina at Chapel Hill, NC 27599, USA, 2Department of Mathematics, Reykjavik University, Reykjavik, Iceland, 3Department of Clinical Laboratory Sciences, University of Cape Town, Rondebosch, Cape Town, 7701, South Africa, 4Department of Statistics, 1 South Parks Road, University of Oxford, OX1 3TG, UK and 5Bioinformatics Research Centre, Aarhus University, C.F.
