Type Parameters:

S - each Sequence of the alignment pair is of type S

C - each element of an AlignedSequence is a Compound of type C

public class SmithWaterman<S extends Sequence<C>,C extends Compound>
extends AbstractPairwiseSequenceAligner<S,C>

Smith and Waterman defined an algorithm for pairwise local sequence alignments (best match of sections from each Sequence). This class performs such local sequence comparisons efficiently by dynamic programming.

Constructor Detail

SmithWaterman

public SmithWaterman()

Before running a pairwise local sequence alignment, data must be sent in via calls to AbstractPairwiseSequenceAligner.setQuery(Sequence), AbstractPairwiseSequenceAligner.setTarget(Sequence), AbstractMatrixAligner.setGapPenalty(GapPenalty), and AbstractMatrixAligner.setSubstitutionMatrix(SubstitutionMatrix).

SmithWaterman

public SmithWaterman(S query,
                     S target,
                     GapPenalty gapPenalty,
                     SubstitutionMatrix<C> subMatrix)

Prepares for a pairwise local sequence alignment.

Parameters:

query - the first Sequence of the pair to align

target - the second Sequence of the pair to align

gapPenalty - the gap penalties used during alignment

subMatrix - the set of substitution scores used during alignment
