Influence of the parameter α 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 parameter α from 200 to 500 Da and fixed parameter settings δ=900, β=250, λ=∞ (no masses are removed in the spectral preprocessing), and the error tolerance ε=0.02 Da
