Pathway analysis in metabolomics: Recommendations for the use of over-representation analysis
Fig 5
The effect of compound misidentification by molecular weight (20ppm window) (bars in dark colours) and chemical formula (bars in light colours) on the mean pathway loss rate (lower bars) and mean pathway gain rate (upper bars) averaged over 100 random resamplings at 4% misidentification. Error bars represent standard error of the mean.
