Correctness of dyads predicted by group of genes and taxonomical level. Rows represent genes with annotations in RegulonDB (368 genes), and are ordered by sum of geometric accuracy then by maximal geometric accuracy. Different conditions are represented: choice of upstream sequences (orthologs or predicted leader genes), background model (MONAD or TAXFREQ) and the use of dyads filtering or not. For each condition, the first five columns correspond to decreasing taxonomical levels: Bacteria (Ba.), Proteobacteria (Pr.), Gamma-proteobacteria (Ga.), Enterobacteriales (En.) and Escherichia (Es.). The background color reflects the tradeoff between the PPV (blue channel) and the sensitivity (green channel) as shown on the reference colour scale. A perfect prediction is displayed with a black background. When the predictions do not match any annotated sites, the accuracy is zero with a white background. Yellow background corresponds to NA which means there is not a single discovered dyad or that the analysis could not be performed (not enough sequences to analyze or too redundant sequences).
