Anomaly in Profinder?

Question asked by quarksome on Jul 21, 2020

Hi,

I'm wondering what's causing this anomaly I'm observing in Profinder (v08) using Batch Targeted Feature Extraction. In some of the compound groups generated, it is extracting and showing incorrect EICs.

 

For example, when I click on Compound A, I see that in some samples, the EIC was extracted with Compound B's set of m/z values. This give a very high averaged mass error for Compound A and also incorrect abundances for the samples involved. I manually checked in Qual and I clearly saw that Compound A peak is there. In any case, why would it even extract other compound's EIC?
