Fig. 2From: A graph-based filtering method for top-down mass spectral identificationInfluence of the parameter δ on the SGM filtering algorithm. The filtration efficiency and running time of the SGM filtering algorithm are compared on the EC evaluation data set with various settings of the parameter δ from 500 to 1400 Da and fixed parameter settings α=300 Da, β=200 Da, λ=∞ (no masses are removed in the spectral preprocessing), and the error tolerance ε=0.02 DaBack to article page
