Response of EVM prediction accuracy to varied evidence types and weights. Iterations (30) of randomly weighted evidence types were evaluated by EVidenceModeler (EVM). Iterations 1 to 10 included only the ab initio predictors GlimmerHMM, Fgenesh, and GeneMark.hmm. Iterations 11 to 20 additionally included AAT-nap alignments of nonrice proteins, GeneWise predictions based on nonrice protein homologies, and AAT-gap2 alignments of other plant expressed sequence tags. Iterations 21 to 30 included Program to Assemble Spliced Alignments (PASA) alignment assemblies and corresponding supplement of PASA long-open reading frame (ORF)-based terminal exons. Exon and complete gene prediction sensitivity values resulting from EVM using the corresponding weight combinations are plotted below.
