Average of alternating injections

Hello,

In order to assist you we will need the following:

• Software product you are using (e.g. OpenLab CDS, OpenLab ChemStation, MassHunter Quant)
• Revision of the software you are using (found by going to either Help>About or File>About)

I use openlab CDs

Hello,

Is there something in common between the injections that you want to average(sample name, vial position, label, ect.) Below is a CC example that averages peak areas for identified peaks for all injections in the same vial.

CurrentSequence.AllIdentifiedPeaks.Where(function (x) x.Compound_Name = CurrentPeakOrGroup.Compound_Name).Where(function (x) x.Injection.Sample.Sample_VialNumber = CurrentInjection.Sample.Sample_VialNumber).Select(function(x) x.Peak_Area).Average

Hello,

This CC would average the current injection with the next by Sample_OrderNumber in the result set. This would be a more generic way to get the average. 

CurrentSequence.AllIdentifiedPeaks.Where(function (x) x.Compound_Name = CurrentPeakOrGroup.Compound_Name).Where(function(x) x.Injection.Sample.Sample_OrderNumber = CurrentSample.Sample_OrderNumber Or x.Injection.Sample.Sample_OrderNumber = (CurrentSample.Sample_OrderNumber +1)).Select(function(x) x.Peak_Area).Average
