  1. Results for the 10-mix data set. Intn, CS and dM denote the normalized intensity, detectable charge states and the mass deviation from the true mass, respectively. When FPR = 0.1, BPDA was able to detect all 10 true peptides, while OpenMS detected only 3 peptides (marked by *). OpenMS achieved its highest TPR (0.6) when FPR = 0.3.
