Error: Unknown or invalid section, "CHROMATOGRAPHY".
Warning: The "Metabolite" column at position 1 in the ["NMR_METABOLITE_DATA"]["Data"] table has all null values.
Warning: The "5p" column at position 2 in the ["NMR_METABOLITE_DATA"]["Data"] table has all null values.
Warning: The "95p" column at position 3 in the ["NMR_METABOLITE_DATA"]["Data"] table has all null values.
