Comparison of W-patterns with randomly generated patterns

	Number of predicted blocks	Number of blocks in average	Length of predicted blocks in average	Cluster propensity
W-patterns	1011	4.7	10	92.7%
Randomly generated patterns (average of 10 rounds)	1041	4.8	9.4	80.1%

The clustering propensity of W-patterns generated by WildSpan was compared with randomly generated patterns. The experiments were tested on the 217 of 220 protein chains (PP220) in the protein-protein benchmark (no homologues can be found for the three cases: 1ml0_A, 1ml0_B, 1udi_I).
