Overlapping performance for DirecTag and InsPecT. These Venn diagrams describe the overlap in spectra with valid tags. The precursor ion charge was a better predictor of overlap than the instrument that produced the spectra. These two algorithms were more similar in spectra from doubly charged precursors than in spectra from triply charged precursors.
