From: A novel series of compositionally biased substitution matrices for comparing Plasmodium proteins
Entropies of biased substitution matrices at different clustering percentages. A series of substitution matrices were constructed from a subset of 1834 biased multiple alignments in BLOCKS data base. Sequences in multiple alignments were grouped by hierarchical (green line) and non-hierarchical clustering (blue line) procedures at different percentage of identity. For every matrix, the corresponding entropy value was calculated.
