(A) SAC values associated with hits located in coding and (B) intergenic regions of E. coli vs. randomized E. coli background; (C) SAC values associated with hits located in divergent, (D) convergent and (E) upstream intergenic regions, preceded by schematic representation of the intergenic region classification; On each plot, SAC values are shown as a function of the growing number of hits per spacer, with confidence bound estimates provided for the SAC values associated with randomized background.
