Constructor Detail

PositionMap

public PositionMap(double scaleFactor)

Constructs a new PositionMap instance.

Parameters:

scaleFactor - the factor that is multiplied by a base position to obtain the corresponding genetic map position

Throws:

java.lang.IllegalArgumentException - if scaleFactor <= 0d || Double.isFinite(scaleFactor) == false

Method Detail

scaleFactor

public double scaleFactor()

Returns the scale factor that is multiplied by the chromosome position to obtain the corresponding genetic map position

Returns:

the scale factor.

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
