extractArrivalRateFileIntoSequenceBinarySplits

public static void extractArrivalRateFileIntoSequenceBinarySplits(Sequence root,
 List<ArrivalRateTuple> arrList,
 double period,

                                                           throws CalibrationException

Extract an arrival Rate file using the simple extraction process.

Parameters:

root - the root
