Choosing the substitution matrix. Comparison of the performances of FASTA and SeqKernel (β,k max )=(0.2,10), as measured by AUC values, for different input substitution matrices, namely the BLOSUM30 (BL30), BLOSUM62 (BL62), BLOSUM90 (BL90), and the Identity matrices. The two values for FASTA and for Seqkernel correspond to the two datasets CATH2833 and CATH793, respectively
