Figure 3From: Towards comprehensive structural motif mining for better fold annotation in the "twilight zone" of sequence dissimilarityExample of frequent subgraphs and approximate frequent subgraphs. Given the graph database D in Figure 2 and the support threshold σ = 2/3,the left side shows the frequent subgraphs mined by the general exact graph mining. Given the compatibility matrix M in Figure 2, isomorphism threshold τ = 0: 4, and support threshold σ = 2/3. The right side presents the frequent approximate subgraphs in D.Back to article page
