Figure 4From: Protein sequence alignment with family-specific amino acid similarity matricesThe scatter plot of the average difference between the elements of the family-specific matrices and the VTML200 matrix. Each dot represents one amino acid pair (210 total). A positive value of the average difference D 1(i, j) (Eq.9) indicates that amino acid pair (i, j) tends to receive a higher score in the family-specific matrices compared to VTML200 and vice versa.Back to article page
