Constructor Detail

BasicAlleleProbs

public BasicAlleleProbs(HapAlleleProbs[] alProbs)

Construct a new BasicAlleleProbs instance from the specified data.

Parameters:

alProbs - allele probabilities for each haplotype

Throws:

java.lang.IllegalArgumentException - if alProbs[j].markers().equals(alProbs[k].markers) == false for any j, k satisfying (0 <= j && j < k && k < alProbs.length)

java.lang.IllegalArgumentException - if alProbs[j].samples().equals(alProbs[k].samples) == false for any j, k satisfying (0 <= j && j < k && k < alProbs.length)

java.lang.IllegalArgumentException - if alProbs.length == 0 || alProbs.length != alProbs[0].nMarkers()

java.lang.NullPointerException - if alProbs == null || alProbs[j] == null for any j satisfying (0 <= j && j < alProbs.length)

Method Detail

alProb1

public float alProb1(int marker,
                     int sample,
                     int allele)

Description copied from interface: AlleleProbs

Returns the probability that the specified marker allele is present on the first haplotype of the specified sample.

Specified by:

alProb1 in interface AlleleProbs

Parameters:

marker - a marker index

sample - a sample index

allele - an allele index

Returns:

the probability that the specified marker allele is present on the first haplotype of the specified sample

alProb2

public float alProb2(int marker,
                     int sample,
                     int allele)

Description copied from interface: AlleleProbs

Returns the probability that the specified marker allele is present on the second haplotype of the specified sample.

Specified by:

alProb2 in interface AlleleProbs

Parameters:

marker - a marker index

sample - a sample index

allele - an allele index

Returns:

the probability that the specified marker allele is present on the second haplotype of the specified sample.

gtProb

public float gtProb(int marker,
                    int sample,
                    int allele1,
                    int allele2)

Description copied from interface: AlleleProbs

Returns the phased genotype probability, equal to (this.allele1(marker, sample, allele1) * this.allele2(marker, sample, allele2)).

Specified by:

gtProb in interface AlleleProbs

Parameters:

marker - a marker index

sample - a sample index

allele1 - allele index of the allele on the first haplotype

allele2 - allele index of the allele on the second haplotype

Returns:

the phased genotype probability equal to (this.allele1(marker, sample, allele1) * this.allele2(marker, sample, allele2))
