Simple Nucleotide Substitution
This is an ad-hoc matrix which, in addition to penalising mutations between the common nucleotides (ACGT), includes T/U equivalence in order to allow both DNA and/or RNA. In addition, it encodes weak equivalence between R and Y with AG and CTU, respectively, and N is allowed to match any other base weakly. This matrix also includes I (Inosine) and X (Xanthine), but encodes them to weakly match any of (ACGTU), and unfavourably match each other. @@ -109,5 +112,100 @@ In addition, it encodes weak equivalence between R and Y with AG and CTU, respec - introduce a nucleotide substitution matrix that supports RNA/DNA and ambiguity codes +
