The predicted regulons were obtained by applying a site search to the genome of E. coli with a threshold score of P < 0.05. The regulogs were obtained by applying Regulogger to the obtained regulons. The genomes that were used for filtering were Yersinia pestis, Pseudomonas aeruginosa, Haemophilus influenzae, and Vibrio cholerae. The efficiency of Regulogger (EfREG) was calculated by comparing the specificity and sensitivity of the regulon and regulog predictions as described in the text.
