Optimal alignment score distribution. The distribution of 10,000 optimal local alignment scores between the shuffles of random profiles of lengths 1,500. Solid line represents the best-fit extreme value distribution. (a) WeightedLogOdds: A χ2 goodness-of-fit test with 43 degrees of freedom has value 35.46, corresponding to a P-value of 0.79 (b) CrossProduct: df = 37, χ2 = 32.47, P-value = 0.68 (c) JensenShannon: df = 39, χ2 = 25.38, P-value = 0.95 (d) Multinomial: df = 39, χ2 = 48.0, P-value = 0.15.
