Figure 1From: Modular decomposition of protein-protein interaction networksA graph and its modules. By definition, a module is a set of nodes that have the same neighbors outside the module. In addition to the trivial modules {a},{b},...,{g} and {a,b,c,..,g}, this graph contains the modules {a,b,c}, {a,b},{a,c},{b,c} and {e,f}.Back to article page
