Figure 4From: NITPICK: peak identification for mass spectrometry dataEvaluation and comparison with the pepex algorithm on simulated data. Accuracy (top left), negative predictive values (top right), positive predictive values (bottom left) and sensitivity-specificity traces (bottom right). Plots show NITPICK results in solid red, NITPICK resultswithout postprocessing in dashed blue and pepex results (optimized, see text) in dashed-dotted black.NITPICK is clearly superior in terms of accuracy, specificity and sensitivity.Back to article page
