Figure 2
From: Protein sequence alignment with family-specific amino acid similarity matrices
The scatter plot of the average difference in the alignment quality score between the family-specific matrices and the VTML200 matrix. Each dot represents one group from the SUP subset. A positive value of the average difference indicates that the family-specific similarity matrix performs better than VTML200. The Pearson's correlation coefficient calculated using the data points from this plot is 0 (no correlation).
