a
Modules are numbered sequentially starting from zero and are prefixed with the letter M. Clusters within a module are numbered sequentially and are prefixed with the letter C. Modules and clusters are prefixed with a species abbreviation: Os for rice and Zm for maize. Thus, cluster 1 from module 8 in rice is named OsM8C1.
b
<k> is the average connectivity of the nodes in the cluster.
c
E-score is the enrichment score, or geometric mean of the Fisher’s test enrichment P values of the cluster.
