Issue Log:
Error: The value, "4 weeks 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, "Medium", in ["MS"]["COLLISION_GAS"] should be one of "Nitrogen" or "Argon". Ignore this when more complicated descriptions are required.
Error: The value, "0.5ml/min", 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, "40", 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: The ["MS_METABOLITE_DATA"]["Metabolites"] table does not have a column for "Metabolite". It is likely misspelled or using a common incorrect substitute.
