Type I errors for KEGG metabolic pathways in the metabolomics data [39]. The x-axis shows the pathway size and the y-axis indicates the type I error. Overlapping points were re-positioned by adding ± 1 to the x-axis and ± 0.01 to the y-axis. CAMERA, DEGraph and PathNet have controlled type I errors, but NetGSA’s type I errors are slightly inflated for several pathways
