Figure 1.

An example of two GO categories, gene co-function network and gene set association. (a and b) An example of two GO categories, in which each node is a GO term, each edge represents a conceptual relation between two terms, and {g1...g13} is the set of genes annotated to corresponding terms. (c) An example of gene co-function network, in which each node is a gene, each edge represents the functional associations between the genes, and the confidence score at each edge measures the probability of an interaction to represent a true functional linkage between two genes. (d) The gene set association between gene set Gb and Gj.
