Fig. 6From: Informed baseline subtraction of proteomic mass spectrometry data aided by a novel sliding window algorithmAn illustration of the proposed algorithm for determining approximate peak widths prior to baseline subtraction. a A Fiedler spectrum with the lower convex hull and repeated (r=5) lower convex hulls. b The lower convex hull subtracted spectrum with median intensity of the spectrum depicted. Points above the median are considered peaks, which have been filled with solid blue shading surrounded by an orange borderBack to article page
