Package org.biojava.nbio.alignment

Class FractionalSimilarityScorer<S extends Sequence<C>,C extends Compound>

java.lang.Object

org.biojava.nbio.alignment.template.AbstractScorer

org.biojava.nbio.alignment.FractionalSimilarityScorer<S,C>

Type Parameters:

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

C - each element of a sequence is a Compound of type C

All Implemented Interfaces:

PairwiseSequenceScorer<S,C>, Scorer

Direct Known Subclasses:

FractionalSimilarityInProfileScorer

public class FractionalSimilarityScorer<S extends Sequence<C>,C extends Compound>
extends AbstractScorer
implements PairwiseSequenceScorer<S,C>

Implements an algorithm which computes a score for a sequence alignment pair. The reported score is the number of alignment columns which have similar Compounds.

Constructor Details

FractionalSimilarityScorer

public FractionalSimilarityScorer(PairwiseSequenceAligner<S,C> aligner)

Creates a fractional similarity scorer for a pair of sequences aligned by the given pairwise sequence aligner.

Parameters:

aligner - a pairwise sequence aligner

FractionalSimilarityScorer

public FractionalSimilarityScorer(SequencePair<S,C> pair)

Creates a fractional similarity scorer for an aligned pair of sequences.

Parameters:

pair - an aligned pair of sequences

Method Details

getQuery

public S getQuery()

Description copied from interface: PairwiseSequenceScorer

Returns the first sequence of the pair.

Specified by:

getQuery in interface PairwiseSequenceScorer<S extends Sequence<C>,C extends Compound>

Returns:

the first sequence of the pair

getTarget

public S getTarget()

Description copied from interface: PairwiseSequenceScorer

Returns the second sequence of the pair.

Specified by:

getTarget in interface PairwiseSequenceScorer<S extends Sequence<C>,C extends Compound>

Returns:

the second sequence of the pair

getMaxScore

public double getMaxScore()

Description copied from interface: Scorer

Returns maximum possible score.

Specified by:

getMaxScore in interface Scorer

Returns:

maximum possible score

getMinScore

public double getMinScore()

Description copied from interface: Scorer

Returns minimum possible score.

Specified by:

getMinScore in interface Scorer

Returns:

minimum possible score

getScore

public double getScore()

Description copied from interface: Scorer

Returns score resulting from algorithm. This should normalize between 0 and 1 by calculating (Scorer.getScore() - Scorer.getMinScore()) / (Scorer.getMaxScore() - Scorer.getMinScore()).

Specified by:

getScore in interface Scorer

Returns:

score resulting from algorithm
