Description
Set of rules to allow selection of peaks from an input time series.
Attributes
In the configuration of peak selections there are two choices for refining the selection:
- An attribute "totalNumberBeforeT0" must be defined. The value attribute defines the maximum number of peaks to consider before T0.
- An attribute "totalNumberAfterT0" must be defined. The value attribute defines the maximum number of peaks to consider after T0.
- An attribute "skipJustBeforeT0" indicates how many peaks to skip just before T0. (optional)
- An attribute "skipJustAfterT0" indicates how many peaks to skip just after T0. (optional)
or
- An attribute "totalNumber" must be defined. The value attribute defines the maximum number of peaks to consider.
Configuration example
SelectionPeaksFunctionTest 1.00 default.xml
<transformation id="peaks function test"> <selection> <peaks> <inputVariable> <timeSeriesSet> <moduleInstanceId>SelectionPeaksFunctionTest</moduleInstanceId> <valueType>scalar</valueType> <parameterId>H.tidal</parameterId> <locationId>H-2010</locationId> <timeSeriesType>external historical</timeSeriesType> <timeStep unit="minute" multiplier="15"/> <relativeViewPeriod unit="day" start="0" end="365"/> <readWriteMode>editing visible to all future task runs</readWriteMode> </timeSeriesSet> </inputVariable> <totalNumberBeforeT0>3</totalNumberBeforeT0> <totalNumberAfterT0>4</totalNumberAfterT0> <skipJustBeforeT0>2</skipJustBeforeT0> <skipJustAfterT0>2</skipJustAfterT0> <outputVariable> <timeSeriesSet> <moduleInstanceId>SelectionPeaksFunctionTest</moduleInstanceId> <valueType>scalar</valueType> <parameterId>H.updated</parameterId> <locationId>H-2010</locationId> <timeSeriesType>external historical</timeSeriesType> <timeStep unit="nonequidistant"/> <relativeViewPeriod unit="day" start="-5" end="15"/> <readWriteMode>add originals</readWriteMode> </timeSeriesSet> </outputVariable> </peaks> </selection> </transformation>
In this example:
- Only the last three lows before T0 and the first four lows after T0 are considered.
- The first two lows just before T0 are skipped, leaving only the third last one.
- Similarly the first lows just after T0 are skipped, leaving the third and fourth ones.
