We identified 979 unique metabolite features based on mass-charge ratios (m/z) using flow-injection ToF-MS, respectively. Of these features, 699 could be attributed to a single metabolite, including in cases where of the two “possible” enantiomers, one is clearly far more predominant than the other (e.g. L versus D amino acids). The remaining 280 metabolites were “clusters” with no clear predominant feature—for example, the “glucose” metabolite measurements could not be separated from fructose, galactose, or mannose measurements, as all share the same m/z. The “main” metabolite, as well as all possible alternatives are listed with the data on GeneNetwork.org for the raw file download (press the “INFO” button next to the dataset on the main search page and download the dataset and supplemental data files).
