A reliable computational tool for identifying such structures would be very useful in guiding experimental analyses of their biological functions. NASP (Nucleic Acid Structure Predictor) is a program that takes into account thermodynamic stability, Boltzmann base pair probabilities, alignment uncertainty, covarying sites and evolutionary conservation to identify biologically relevant secondary structures within multiple sequence alignments. Unique to NASP is the consideration of all this information together with a recursive permutation-based approach to progressively identify and list the most conserved probable secondary structures that are likely to have the greatest biological relevance. By focusing on identifying only evolutionarily conserved structures, NASP forgoes the prediction of complete nucleotide folds but outperforms various other secondary structure prediction methods in its ability to selectively identify actual base pairings.<\/jats:p>\n               <jats:p>Availability: Downloable and web-based versions of NASP are freely available at http:\/\/web.cbio.uct.ac.za\/~yves\/nasp_portal.php<\/jats:p>\n               <jats:p>Contact: \u00a0yves@cbio.uct.ac.za<\/jats:p>\n               <jats:p>Supplementary information: \u00a0Supplementary data are available at Bioinformatics online.<\/jats:p>","DOI":"10.1093\/bioinformatics\/btr417","type":"journal-article","created":{"date-parts":[[2011,7,15]],"date-time":"2011-07-15T00:34:59Z","timestamp":1310690099000},"page":"2443-2445","source":"Crossref","is-referenced-by-count":8,"title":["NASP: a parallel program for identifying evolutionarily conserved nucleic acid secondary structures from nucleotide sequence alignments"],"prefix":"10.1093","volume":"27","author":[{"given":"J.
