The Twinscan program predicts genes in a manner similar to Genscan, except that Twinscan takes advantage of genome comparison to improve gene prediction accuracy. More information and a web server can be found at http://genes.cs.wustl.edu/. Human genome assembly Build 33 (hg15) was used to generate this set of predictions.
The Twinscan algorithm is described in Korf I, Flicek P, Duan D, and Brent MR (2001), "Integrating genomic homology into gene structure prediction", Bioinformatics 17:S140-148.
