The Functions available at each level are explained in the Description field in the application.
The syntax explains how to use the function. The examples are formulas that can be directly used in a Custom Calculation file. You can copy each example and paste it into a Formula field.
Some functions are available at several levels. The result of the formula will depend on the level where the function is called.
For example, AllIdentifiedPeaks can be called from a sequence, an injection or a signal level:
Count(CurrentSequence.AllIdentifiedPeaks) returns the number of identified peaks within the current sequence
Count(CurrentInjection.AllIdentifiedPeaks) returns the number of identified peaks within the current injection
Count(CurrentSignal.AllIdentifiedPeaks) returns the number of identified peaks within the current signal
