Table 2 Amino acid substitution matrix optimized for the LA kernel (β = 0:5). Optimization was started from the BLOSUM62 matrix with gap open and extension penalties initialized to 12 and 2 respectively, on COG training data. After the optimization procedure, the gap open and extension penalties are 12.5 and 5.0, respectively.
