The technology produces signal spectra that contain information about the chemical dissociation pattern of a peptide that was forced to fragment using methods like collision-induced dissociation. The ability to predict these MS2 signals and to understand this fragmentation process is important for sensitive high-throughput proteomics research.<\/jats:p>\n               <jats:p>Results: We present a new tool called MS2PIP for predicting the intensity of the most important fragment ion signal peaks from a peptide sequence. MS2PIP pre-processes a large dataset with confident peptide-to-spectrum matches to facilitate data-driven model induction using a random forest regression learning algorithm. The intensity predictions of MS2PIP were evaluated on several independent evaluation sets and found to correlate significantly better with the observed fragment-ion intensities as compared with the current state-of-the-art PeptideART tool.<\/jats:p>\n               <jats:p>Availability: MS2PIP code is available for both training and predicting at http:\/\/compomics.com\/.<\/jats:p>\n               <jats:p>Contact: \u00a0sven.degroeve@UGent.be<\/jats:p>\n               <jats:p>Supplementary information: \u00a0Supplementary data are available at Bioinformatics online.<\/jats:p>","DOI":"10.1093\/bioinformatics\/btt544","type":"journal-article","created":{"date-parts":[[2013,9,29]],"date-time":"2013-09-29T00:25:21Z","timestamp":1380414321000},"page":"3199-3203","source":"Crossref","is-referenced-by-count":167,"title":["MS2PIP: a tool for MS\/MS peak intensity prediction"],"prefix":"10.1093","volume":"29","author":[{"given":"Sven","family":"Degroeve","sequence":"first","affiliation":[{"name":"1 Department of Medical Protein Research, VIB, Ghent 9000, Belgium and 2Department of Biochemistry, Ghent University, Ghent 9000, Belgium"},{"name":"1 Department of Medical Protein Research, VIB, Ghent 9000, Belgium and 2Department of Biochemistry, Ghent University, Ghent 9000, Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lennart","family":"Martens","sequence":"additional","affiliation":[{"name":"1 Department of Medical Protein Research, VIB, Ghent 9000, Belgium and 2Department of Biochemistry, Ghent University, Ghent 9000, Belgium"},{"name":"1 Department of Medical Protein Research, VIB, Ghent 9000, Belgium and 2Department of Biochemistry, Ghent University, Ghent 9000, Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2013,9,27]]},"reference":[{"key":"2023012810481768600_btt544-B1","first-page":"219","article-title":"A machine learning approach to predicting peptide fragmentation spectra","volume-title":"Pacific Symposium on Biocomputing","author":"Arnold","year":"2006"},{"key":"2023012810481768600_btt544-B2","doi-asserted-by":"crossref","first-page":"177","DOI":"10.1002\/mas.20188","article-title":"Review of factors that influence the abundance of ions produced in a tandem mass spectrometer and statistical methods for discovering these factors","volume":"28","author":"Barton","year":"2009","journal-title":"Mass Spectrom.
