From: NITPICK: peak identification for mass spectrometry data
Evaluation 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.
