A) Bisulfite seed table, using the original seed and bisulfite variants as keys and
corresponding coordinates in the reference genome as values. Each read was looked up in
the seed table for potential mapping positions. B) A positional specific mask of the
corresponding reference sequence was generated by setting 01 to C(light blue) and 11 to A,
G, T(black). The original read was masked by a bitwise AND operation with the positional
specific mask. C) The reference sequence and the masked read were compared with a
bitwise XOR operation. Non-zero XOR results were counted as mismatches (red). Bisulfite
alignment is marked in green.
