Method Details

computeMatrixSimilarity

public Double computeMatrixSimilarity(Gene gene1,
 Gene gene2,
 DoubleMatrix<Long,String> gene2TermMatrix,
 GoMetric.Metric metric)

Specified by:

computeMatrixSimilarity in interface GoMetric

computeMaxSimilarity

public Double computeMaxSimilarity(Gene queryGene,
 Gene targetGene,
 Map<String,Double> GOProbMap,
 GoMetric.Metric metric)

Specified by:

computeMaxSimilarity in interface GoMetric

Parameters:

queryGene - query gene

targetGene - target gene

GOProbMap - go prob map

metric - metric

Returns:

the MAX overlap score between two genes

computeMergedOverlap

public Double computeMergedOverlap(List<Gene> sameGenes1,
 List<Gene> sameGenes2,
 Map<Long,Collection<String>> geneGoMap)

Tailored to handle computing overlap between two gene lists which may contain duplicate genes of the same name but different IDs. If gene lists do not contain duplicates (size = 1) the result will be the same as that of computing simple overlap.

Specified by:

computeMergedOverlap in interface GoMetric

Parameters:

sameGenes1 - same genes 1

sameGenes2 - same genes 2

geneGoMap - gene go map

Returns:

number of overlapping terms between merged sets of GO terms for duplicate gene lists

computeSimilarity

public Double computeSimilarity(Gene queryGene,
 Gene targetGene,
 Map<String,Double> GOProbMap,
 GoMetric.Metric metric)

Specified by:

computeSimilarity in interface GoMetric

Parameters:

queryGene - query gene

targetGene - target gene

GOProbMap - go prob map

metric - metric

Returns:

the overlap score between two genes

computeSimpleOverlap

public Double computeSimpleOverlap(Gene g,
 Gene coexpG,
 Map<Long,Collection<String>> geneGoMap)

Specified by:

computeSimpleOverlap in interface GoMetric

Parameters:

g - g

coexpG - coexp g

geneGoMap - gene go map

Returns:

number of overlapping terms

createVectorMatrix

public DoubleMatrix<Long,String> createVectorMatrix(Map<Long,Collection<String>> gene2go,
 boolean weight)

Specified by:

createVectorMatrix in interface GoMetric

Parameters:

gene2go - Map

weight - weight

Returns:

Sparse matrix of genes x GOTerms

getChildrenOccurrence

public Integer getChildrenOccurrence(Map<String,Integer> termCountMap,
 String term)

Specified by:

getChildrenOccurrence in interface GoMetric

Parameters:

termCountMap - each GO term uri mapped to the number of its occurrence in the corpus

term - the uri of the query GO term

Returns:

the number of times the query GO term occurs in addition to the number of times its children occur in the corpus

setGene2GOAssociationService

public void setGene2GOAssociationService(Gene2GOAssociationService gene2GOAssociationService)

Specified by:

setGene2GOAssociationService in interface GoMetric

Parameters:

gene2GOAssociationService - the gene2GOAssociationService to set

setGeneOntologyService

public void setGeneOntologyService(GeneOntologyService geneOntologyService)

Specified by:

setGeneOntologyService in interface GoMetric

Parameters:

geneOntologyService - the geneOntologyService to set

logIds

protected void logIds(String prefix,
 Collection<OntologyTerm> terms)
