For this, new transcripts must be accurately detected from intensity time traces.<\/jats:p>\n               <jats:p>Results : We present a novel method for automatically estimating RNA numbers and production intervals from temporal data of cell fluorescence intensities that reduces uncertainty by exploiting temporal information. We also derive a robust variant, more resistant to outliers caused e.g. by RNAs moving out of focus. Using Monte Carlo simulations, we show that the quantification of RNA numbers and production intervals is generally improved compared with previous methods. Finally, we analyze data from live Escherichia coli and show statistically significant differences to previous methods. The new methods can be used to quantify numbers and production intervals of any fluorescent probes, which are present in low copy numbers, are brighter than the cell background and degrade slowly.<\/jats:p>\n               <jats:p>Availability : Source code is available under Mozilla Public License at http:\/\/www.cs.tut.fi\/%7ehakkin22\/jumpdet\/ .<\/jats:p>\n               <jats:p>Contact : andre.ribeiro@tut.fi<\/jats:p>","DOI":"10.1093\/bioinformatics\/btu592","type":"journal-article","created":{"date-parts":[[2014,9,5]],"date-time":"2014-09-05T05:34:33Z","timestamp":1409895273000},"page":"69-75","source":"Crossref","is-referenced-by-count":13,"title":["Estimation of GFP-tagged RNA numbers from temporal fluorescence intensity data"],"prefix":"10.1093","volume":"31","author":[{"given":"Antti","family":"H\u00e4kkinen","sequence":"first","affiliation":[{"name":"Laboratory of Biosystem Dynamics, Computational Systems Biology Research Group, Department of Signal Processing, Tampere University of Technology, P.O. box 553, 33101 Tampere, Finland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andre S.","family":"Ribeiro","sequence":"additional","affiliation":[{"name":"Laboratory of Biosystem Dynamics, Computational Systems Biology Research Group, Department of Signal Processing, Tampere University of Technology, P.O. box 553, 33101 Tampere, Finland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2014,9,3]]},"reference":[{"key":"2023020116155810900_btu592-B1","doi-asserted-by":"crossref","first-page":"3117","DOI":"10.1039\/c3mb70203k","article-title":"Temperature dependence of the LacI-TetR-CI repressilator","volume":"9","author":"Chandraseelan","year":"2013","journal-title":"Mol.
