Column 1 lists the average of the pairwise Pearson’s correlation coefficients of expression values of genes in these modules. Column 2* reports the most significantly enriched GO biological process in each module that has the smallest p-value. Column 3 lists the number of TFs predicted for a module. Column 4 lists the number of genes in a module that had GO annotations. Column 5 lists the percent of genes in each module participating in the biological process. Column 6 (I$) shows if at least two predicted TFs in a module interacted according to the STRING predictions and the BLAST homology search. Evidence sources for STRING predictions include E - experiments; Ce - co-expression; T – text mining; H - homology. Column 7 (M&) reports if the DNA binding motifs of some predicted TF families in a module matched the motifs extracted from the upstream sequences of the regulated genes in the module. Column 8 (L#) lists if previous literature had reported a relationship amongst at least one predicted TF family, a stress condition, and the predicted gene function of a module.
