Variation in generalised operon gene expression. Box plot diagrams for all Zop,i values calculated for genes at position k in (a) all known S. coelicolor operons, (b) adjacent genes known not to be in an operon in S. coelicolor, (c) all known E. coli operons, and (d) adjacent genes known not be in an operon in E. coli.
