Issue Log:
Error: An empty value or a null value was detected in ["STUDY"]["NUM_MALES"]. Either a legitimate value should be provided for this key, or it should be removed altogether.
Error: An empty value or a null value was detected in ["STUDY"]["NUM_FEMALES"]. Either a legitimate value should be provided for this key, or it should be removed altogether.
Error: The value, "40-50", in ["CHROMATOGRAPHY"]["COLUMN_TEMPERATURE"] should be a number or range (ex. "5-6") followed by a space with a unit (ex. "5 V") from the following list: ['°C', 'C']. Ignore this when more complicated descriptions are required.
Warning: There is a metabolite name, "Metabolite_name", in the table at ["MS_METABOLITE_DATA"]["Metabolites"] that is probably wrong. It is close to a header name and is likely due to a badly constructed Tab file.
Error: The ["MS_METABOLITE_DATA"]["Data"] table does not have a column for "Metabolite". It is likely misspelled or using a common incorrect substitute.
