  1. Three substitution matrices are built-in to the homolmapper application ("built-in"), while the others are supplied as external matrices that can be loaded at runtime if so desired. Some of the external matrices are supplied in a compressed archive ("compressed"), while others are not ("external file"). The expanded BLOSUM62 and PAM250 schemes (*) incorporate standard values for 'B,' 'X,' and 'Z' amino acids.
