Methods

Modifier and Type	Method and Description
boolean	addLocationInformation(java.lang.String readName, OpticalDuplicateFinder.PhysicalLocation loc) Method used to extract tile/x/y from the read name and add it to the PhysicalLocation so that it can be used later to determine optical duplication
boolean[]	findOpticalDuplicates(java.util.List<? extends OpticalDuplicateFinder.PhysicalLocation> list) Finds which reads within the list of duplicates are likely to be optical duplicates of one another.

Method Detail

addLocationInformation

public boolean addLocationInformation(java.lang.String readName,
                             OpticalDuplicateFinder.PhysicalLocation loc)

Method used to extract tile/x/y from the read name and add it to the PhysicalLocation so that it can be used later to determine optical duplication

Parameters:

readName - the name of the read/cluster

loc - the object to add tile/x/y to

Returns:

true if the read name contained the information in parsable form, false otherwise

findOpticalDuplicates

public boolean[] findOpticalDuplicates(java.util.List<? extends OpticalDuplicateFinder.PhysicalLocation> list)

Finds which reads within the list of duplicates are likely to be optical duplicates of one another.

Note: this method will perform a sort() of the list; if it is imperative that the list be unmodified a copy of the list should be passed to this method.

Parameters:

list - a list of reads that are determined to be duplicates of one another

Returns:

a boolean[] of the same length as the incoming list marking which reads are optical duplicates
