I assume you want to see this in a QC folder. As you point out, you can select "Mass Accuracy" as a metric for the QC plots. As it is implemented right now, it will show you the average mass error across all fragment ions of the precursor. If you have precursor ions (M, M+1, M+2) those are included in getting the average. I think we want to separate these by precursor and fragment ions as we do with the "Transition / Precursor Areas" metric. Does that sound like what you would like to see?
Yes. If we could see the mass accuracy split between the precursor ion (M, M+1, M+2) and the mass accuracy of the product ions that would help us a bit. This would allow us to see the mass accuracy of both detectors in the fusion style hybrid instrument to confirm when we should calibrate and which part of the instrument we should calibrate.
Is something like this possible?
