*network scores given in the parentheses were based in the hyper geometric distribution and were calculated with the right-tailed Fisher’s Exact Test. The scores were not an indication of the quality or biological relevance of the network; they simply measured the approximate “fit” between each network and the network eligible molecules.
†p values in the parentheses were associated with a function or a pathway in Global Functional Analysis (GFA) and Global Canonical Pathway (GCP); a measure of the likelihood that the association between a set of focus genes in the experiment and a given process or pathway was due to a random chance.
