Figure 4From: Amino acid "little Big Bang": Representing amino acid substitution matrices as dot products of Euclidian vectorsPlot of the matrix mean (blue), matrix relative entropy (red) and amino acid galaxy radius, R g (black), for the PAM matrix series. As explained in the text, the observed lack of monotonicity of the matrix mean and galaxy radius curves, is probably due to the fact that rounded PAM matrices were used. The x-axis corresponds to PAM matrix indices, from 10 to 500 by increment of 10, the y-axis corresponds to the values.Back to article page
