...
Set of rules to allow selection of peaks from an input time series.
This transformation will select only the peaks which occur within the defined gap in time between peaks.
Input
Timeseries
Options
Requirements for definitions of peak selections using gaps to define independence are:
...
- An attribute "totalNumber" must be defined. The value attribute defines the maximum number of peaks to consider.
Output
Timeseries containing the selection of peaks
