Constructor Detail

DataSetKMerEnumerator

public DataSetKMerEnumerator(DataSet data,
                             int k,
                             boolean eliminateRevComp)
                      throws OperationNotSupportedException

Constructs a new DataSetKMerEnumerator from a DataSet data by extracting all k-mers.

Parameters:

data - the data to extract the k-mers from

k - the length of the k-mers

eliminateRevComp - whether to ignore the reverse complement of already existing k-mers

Throws:

OperationNotSupportedException - if a Sequence in data does not support to compute the reverse complement but eliminateRevComp is true
