A module is defined for every gene as the set of its k top correlating genes by Pearson correlation of temporal expression profiles, where k is the diameter, shown as number of genes and as genome-wide proportion (of 6,082 genes). Sig. modules reports the number and percentage of significant gene modules (P < 1/250) averaged over all pairs of strains. Overlap reports the number of genes overlapping for a given module between a pair of strains, at the specified diameter k, averaged over all significant modules and all pairs of strains. This is also shown in parentheses as a percentage of diameter. Excess shows the excess percentage of overlap compared to random expectation using binomial sampling. The excess percentage averaged over all k is 8.24%.
