Issue Log:
Error: The value, "4-month-old", in ["SUBJECT"]["AGE_OR_AGE_RANGE"] should be a number or range (ex. "5-6") followed by a space with a unit (ex. "5 V") from the following list: ['weeks', 'days', 'months', 'years']. Ignore this when more complicated descriptions are required.
Error: The value in ["SUBJECT"]["WEIGHT_OR_WEIGHT_RANGE"] should be a number or range (ex. "5-6") followed by a space with a unit (ex. "5 V") from the following list: ['g', 'mg', 'kg', 'lbs']. Ignore this when more complicated descriptions are required.
Error: An empty value or a null value was detected in ["CHROMATOGRAPHY"]["FLOW_GRADIENT"]. A legitimate value should be provided for this required key.
Error: The value, "N/A", in ["CHROMATOGRAPHY"]["FLOW_RATE"] should be a number or range (ex. "5-6") followed by a space with a unit (ex. "5 V") from the following list: ['mL/min', 'uL/min', 'μL/min']. Ignore this when more complicated descriptions are required.
Error: The value, "N/A", 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.
Error: An empty value or a null value was detected in ["CHROMATOGRAPHY"]["SOLVENT_B"]. A legitimate value should be provided for this required key.
Error: SUBJECT_SAMPLE_FACTORS section missing sample ID(s). The following IDs were found in the ["MS_METABOLITE_DATA"]["Data"] section but not in the SUBJECT_SAMPLE_FACTORS:
	""
Error: Column(s) with no name were found in the ["MS_METABOLITE_DATA"]["Data"] table.
Warning: The "" column at position 15 in the ["MS_METABOLITE_DATA"]["Data"] table has all null values.
Error: The ["MS_METABOLITE_DATA"]["Metabolites"] table does not have a column for "Metabolite". It is likely misspelled or using a common incorrect substitute.
