Figure 3From: NITPICK: peak identification for mass spectrometry dataComparison of the impact of averagine and fractional averagine stoichiometry estimationerrors on the estimation of theoretical isotope distributions. The cumulative histograms of least squares deviations from the true theoretical isotope distribution illustrate the superior overall performance of fractional averagine (solid line) compared to Senko's classical averagine (dashed line): fractional averagine causes a 17% decrease in mean squared error magnitude.Back to article page
