Crp-Significant Intergenic Regions Found. When counting Crp-significant intergenic regions, comparison of the bars labeled "+" (with the unalignable sequences) relative to those labeled "-" (without the unalignable sequences) indicates that the largest gain in sensitivity comes from the use of unalignable, evolutionarily distant sequences. The left part of this figure shows the sensitivity for the scan of E. coli data only. The center part of this figure shows the sensitivity from the scan of only those E. coli sequence data that are alignable with S. typhi. The right part of this figure shows the sensitivity from the scan of E. coli-S. typhi aligned sequence data.
