Factors affecting gene-finding accuracy. Plots of gene-level sensitivity against features of genes that are correlated with gene-finding accuracy: (A) the lowest hexamer score of any of the exons in the gene, (B) the number of exons in the gene, (C) the length of the shortest exon in the gene, (D) the length of the longest intron in the gene, (E) the strength of the translation start signal, (F) the lowest score of any of splice sites in the gene, (G) the percent identity with the C. briggsae ortholog at the amino acid level, (H) the maximum distance to a neighbouring gene, and (I) the number of isoforms in the gene. In each plot, the submitted gene sets are coloured by nGASP category, with ab initio (category 1) gene sets in red, gene-finders that used multi-genome alignments (category 2) in black, and gene-finders that used transcript/protein alignments (category 3) in blue. The solid lines show the median sensitivities of the gene sets in a category, while the dashed lines show the maximum sensitivity of the gene sets in a category.
