I only want a custom field to calculate for one particular label.
I have an intersample summary custom field that calculates the sum of all areas in a sample with the label R1. But I don't want the custom field populated for any other injection. For this, can I just add something like: R1.%..SUM(Area)+NEQI(Label,"R1")*-1*50000? or maybe multiply the custom field formula by a Bool expression like R1.%..SUM(Area)*(EQ(Label,R1)? I noticed a lot of recent articles on custom fields seem to be doing this eg for peak calculations something like R1.%..AVE(Area)*(EQ(Name,"Caffeine")
