Hello, 
 
 You would need to use a custom calculation in CDS to calculate the data points. As an example, the CC below uses a enter value for data rate in the CCF file to calculate an estimate for the number of points from the peak start and peak end times. You would need to provide the data rate as in the example or using a custom field. This is because the number from the method cannot be accessed for calculations. I compared the calculations to the actual points in excel from the CSV export of the chromatogram.
