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

Guan and Uberbacher 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 with a space requirement reduced from quadratic (a multiple of query sequence length times target sequence length) to only linear (a multiple of query sequence length). The counterpoint to this reduction in space complexity is a modest (a multiple < 2) increase in time.

Constructor Detail

GuanUberbacher

public GuanUberbacher()

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).

GuanUberbacher

public GuanUberbacher(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

GuanUberbacher

public GuanUberbacher(S query,
              S target,
              GapPenalty gapPenalty,
