Issue Log:
Error: The value, "500 and 600 MHz", for the subsection, "SPECTROMETER_FREQUENCY", in the "NM" section should be a number followed by a space with a unit (ex. "5 V") from the following list: ['MHz']. Ignore this when more complicated descriptions are required.
Error: Unknown or invalid section, "CHROMATOGRAPHY".
Warning: SUBJECT_SAMPLE_FACTORS entry #164 has a duplicate Sample ID.
Warning: There are duplicate samples in the NMR_METABOLITE_DATA section.
Error: The NMR_METABOLITE_DATA table does not have a column for "Samples". It is likely misspelled or using a common incorrect substitute.
