Alignment with adaptive bands a Score calculation step. Bands with a width set at 3 are dynamically adjusted by moving downward or to the right, as depicted by blue arrows. Bands are computed from the top-left to the bottom-right along the left diagonal. Each score calculation depends on three previously calculated scores from the left, up, and previous diagonal cells, as bold red arrows show. b Backtracking step. The optimal alignment is found by tracing back from the maximum score along the recorded directional trace flags, as indicated by red arrows
