vcf.MarkerMap

All Implemented Interfaces:

GeneticMap

public class MarkerMap
extends java.lang.Object
implements GeneticMap

Class MarkerMap represents genetic map positions for a list of markers.

Instances of class MarkerMap are immutable.

Method Detail

create

public static MarkerMap create(GeneticMap genMap,
                               Markers markers)

Returns a new MarkerMap instance that is constructed from the specified data

Parameters:

genMap - the genetic map

markers - a list of markers

Returns:

a returns new MarkerMap instance

Throws:

java.lang.IllegalArgumentException - if markers.marker(0).chromIndex() != markers.marker(markers.nMarkers()-1).chromIndex()

java.lang.NullPointerException - if genMap == null || markers == null

chrom

public java.lang.String chrom()

Returns the chromosome corresponding to the list of markers.

Returns:

the chromosome corresponding to the list of markers

chromIndex

public int chromIndex()

Returns the index of the chromosome corresponding to the list of markers.

Returns:

the index of the chromosome corresponding to the list of markers

basePos

public int basePos(int chrom,
                   double geneticPosition)

Description copied from interface: GeneticMap

Returns the base position corresponding to the specified genetic map position. If the genetic position is not a map position then the base position is estimated from the nearest genetic map positions using linear interpolation.

Specified by:

basePos in interface GeneticMap

Parameters:

chrom - the chromosome index

geneticPosition - the genetic position on the chromosome

Returns:

the base position corresponding to the specified genetic map position

genPos

public double genPos(Marker marker)

Description copied from interface: GeneticMap

Returns the genetic map position of the specified marker. The genetic map position is estimated using linear interpolation.

Specified by:

genPos in interface GeneticMap

Parameters:

marker - a genetic marker

Returns:

the genetic map position of the specified marker

genPos

public double genPos(int chrom,
                     int basePosition)

Description copied from interface: GeneticMap

Returns the genetic map position of the specified genome coordinate. The genetic map position is estimated using linear interpolation.

Specified by:

genPos in interface GeneticMap

Parameters:

chrom - the chromosome index

basePosition - the base coordinate on the chromosome

Returns:

the genetic map position of the specified genome coordinate

nMarkers

public int nMarkers()

Returns the number of markers.

Returns:

the number of markers

markers

public Markers markers()

Returns the list of markers.

Returns:

the list of markers

marker

public Marker marker(int marker)

Returns the specified marker.

Parameters:

marker - a marker index

Returns:

the specified marker

genPos

public double genPos(int marker)

Returns the genetic map position of the specified marker.

Parameters:

marker - a marker index

Returns:

the genetic map position of the specified marker

Throws:

java.lang.IndexOutOfBoundsException - if marker < 0 || marker >= this.nMarkers()

genPos

public double[] genPos()

Returns the array of genetic map positions whose k-th element equals this.genPos(k).

Returns:

the array of genetic map positions
