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

All Implemented Interfaces:

Aligner<S,C>, MatrixAligner<S,C>, PairwiseSequenceAligner<S,C>, PairwiseSequenceScorer<S,C>, Scorer

public class NeedlemanWunsch<S extends Sequence<C>,C extends Compound>
extends AnchoredPairwiseSequenceAligner<S,C>

Needleman and Wunsch defined an algorithm for pairwise global sequence alignments (from the first until the last Compound of each Sequence). This class performs such global sequence comparisons efficiently by dynamic programming.

Constructor Detail

NeedlemanWunsch

public NeedlemanWunsch()

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

NeedlemanWunsch

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

Prepares for a pairwise global 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
