Two possible cases where different SNP residues have an overlap in their flanking sequences. There can be two different cases where an overlapping occurs between flanking sequences of two different SNP residues. a Fully overlapped without mismatch, b Partially overlapped with mismatch. In case of (a), two SNP residues are merged into a single sequence to prevent unnecessary long search for K’s. However, in case of (b), we randomly chose one residue and discarded the other one
