Class SplicedGT

java.lang.Object
vcf.SplicedGT
All Implemented Interfaces:
GT
public final class SplicedGT extends Object implements GT

Class SplicedGT represents genotypes for a set of samples that are obtained by replacing the initial markers of one GT instance with phased genotypes from another GT instance.

Instances of class SplicedGT are immutable.

      gt - genotype emission probabilities for all markers
      Throws:
      IllegalArgumentException - if phasedOverlaps.nMarkers() >= gt.nMarkers()
      IllegalArgumentException - if phasedOverlaps.marker(j).equals(gt.marker(j)) == false for any j satisfying 0 <= j && j < phasedOverlaps.nMarkers()
      IllegalArgumentException - if phasedOverlaps.samples().equals(gt.samples()) == false
      IllegalArgumentException - if phasedOverlap.isPhased() == false
      NullPointerException - if phasedOverlap == null || gt == null

    • isReversed

      public boolean isReversed()
      Description copied from interface: GT
      Returns true if the markers are ordered by decreasing chromosome base position, and returns false otherwise.
      Specified by:
      isReversed in interface GT
      Returns:
      true if the markers are ordered by decreasing chromosome base position

    • marker

      public Marker marker(int marker)
      Description copied from interface: GT
      Returns the specified marker.
      Specified by:

    • markers

      public Markers markers()
      Description copied from interface: GT
      Returns the list of markers in order of increasing chromosome position.
