Class BreakpointEvidence

java.lang.Object

org.broadinstitute.hellbender.tools.spark.sv.evidence.BreakpointEvidence

Direct Known Subclasses:

BreakpointEvidence.ExternalEvidence, BreakpointEvidence.ReadEvidence, BreakpointEvidence.TemplateSizeAnomaly

public class BreakpointEvidence
extends java.lang.Object

Various types of read anomalies that provide evidence of genomic breakpoints. There is a shallow hierarchy based on this class that classifies the anomaly as, for example, a split read, or a pair that has both reads on the same reference strand. Each BreakpointEvidence object of type ReadEvidence object comes from examining a single read, and describing its funkiness, if any, by instantiating one of the subclasses that addresses that type of funkiness. Instances of BreakpointEvidence that are not of subtype ReadEvidence consolidate information from one or more pieces of ReadEvidence into a single object.

BreakpointEvidence

public BreakpointEvidence(SVInterval location,
                          int weight,
                          boolean validated)

                             com.esotericsoftware.kryo.io.Input input)

Method Detail

getLocation

public SVInterval getLocation()

getWeight

public int getWeight()

isValidated

public boolean isValidated()

setValidated

public void setValidated(boolean validated)

isEvidenceUpstreamOfBreakpoint

public java.lang.Boolean isEvidenceUpstreamOfBreakpoint()

If true: the evidence suggests a breakpoint at a reference location upstream of the interval's start coordinate If false: the evidence suggests a breakpoint downstream of the interval's end coordinate

hasDistalTargets

public boolean hasDistalTargets(ReadMetadata readMetadata,
                                int minEvidenceMapQ)

Returns true if this piece of evidence specifies a possible distal target for the breakpoint.

Parameters:

readMetadata - Read metadata for the library

minEvidenceMapQ - The minimum mapping quality threshold (inclusive) for which a target (mate or SA mapping) should be created

getDistalTargets

public java.util.List<StrandedInterval> getDistalTargets(ReadMetadata readMetadata,
                                                         int minEvidenceMapq)

Returns the distal interval implicated as a candidate adjacency to the breakpoint by this piece of evidence. For example, in the case of a discordant read pair, this would be the region adjacent to the mate of the current read. Returns null if the evidence does not specify or support a possible targeted region (for example, the case of an read with an unmapped mate). Strands of the intervals indicate whether the distal target intervals are upstream or downstream of their proposed breakpoints: true indicates that the breakpoint is upstream of the interval start position; false indicates that the breakpoint is downstream of the interval end position.

Parameters:

minEvidenceMapq - The minimum mapping quality (inclusive) of the target evidence; if the mapping quality is below this value the evidence is treated as not having a distal target
