  1. The exact m/z value is the monoisotopic mass of the compound suggested for annotation. The error is the relative difference between the experimental neutral m/z value and the exact m/z. The asterisk indicates the metabolite that most likely corresponds to the feature
  2. RT retention time, FC fold change
  3. a Features were annotated based on METLIN and literature review
