Which are the bioinformatics tools for gene structure prediction?

["The prediction of the complete structure of genes is one of the very important tasks of bioinformatics, especially in eukaryotes. A crucial part in the gene structure prediction is to determine the splice sites in the coding region. Identification of splice sites depends on the precise recognition of the boundaries between exons and introns of a given DNA sequence. This problem can be formulated as a classification of sequence elements into 'exon-intron' (EI), 'intron-exon' (IE) or 'None' (N) boundary classes.", 'The proposed WPSS method poses efficient results compared with the performance of many methods proposed in the literature.', 'SCGPred: a score-based method for gene structure prediction by combining multiple sources of evidence.', 'Moreover, computational gene finding in newly sequenced genomes is especially a difficult task due to the absence of a training set of abundant validated genes. Here we present a new gene-finding program, SCGPred, to improve the accuracy of prediction by combining multiple sources of evidence.', 'Therefore, SCG-Pred can serve as an alternative gene-finding tool for newly sequenced eukaryotic genomes. The program is freely available at http://bio.scu.edu.cn/SCGPred/.', 'Incorporation of splice site probability models for non-canonical introns improves gene structure prediction in plants.', 'We pursued one such approach and describe the training and implementation of GC-donor splice site models for Arabidopsis and rice, with the goal of exploring whether specific modeling of non-canonical introns can enhance gene structure prediction accuracy.', 'Source code for the updated versions of GeneSeqer and SplicePredictor (distributed with the GeneSeqer code) isavailable at http://bioinformatics.iastate.edu/bioinformatics2go/gs/download.html.

['The in silico prediction of the complete structure of genes is one of the main challenges of bioinformatics. A critical part in the gene structure prediction is to identify the boundaries between exons and introns (i.e. splice sites) in the coding region. Several advanced bioinformatics tools have been developed for the precise delineation of a given gene structure: WPSS, SCGPred, TICO, GLIMMER, MetWAMer, WebScipio, GeneSeqer,  SplicePredictor, DGSplicer, Transcript Assembly Program (TAP), GeneBuilder, SeqHelp, HSPL, RNASPL, HEXON, CDSB, HBR, FGENE and FGENEH for human genes.', 'SCGPred: a score-based method for gene structure prediction by combining multiple sources of evidence.
