Web7 Mar 2011 · These algorithms generally fall into two categories: global, which align the entire sequence, and local, which only look for highly similar subsequences. This Demonstration uses the Needleman–Wunsch … WebThe Smith–Waterman algorithm has several steps: Determine the substitution matrix and the gap penalty scheme. A substitution matrix assigns each pair of bases or amino acids a score for match or mismatch. Usually matches get positive scores, whereas mismatches get relatively lower scores.
