Issue Log:
Error: The value, "10 day old seedlings", 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, "Not applicable", in ["SUBJECT"]["GENDER"] should be one of "Male", "Female", "Male, Female", "Hermaphrodite", or "N/A". Ignore this when more complicated descriptions are required.
Error: An empty value or a null value was detected in ["SUBJECT_SAMPLE_FACTORS"][48]["Additional sample data"]["RAW_FILE_NAME"]. 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 ["SUBJECT_SAMPLE_FACTORS"][49]["Additional sample data"]["RAW_FILE_NAME"]. 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 ["SUBJECT_SAMPLE_FACTORS"][50]["Additional sample data"]["RAW_FILE_NAME"]. Either a legitimate value should be provided for this key, or it should be removed altogether.

Error: The value, "0.3 mL min-1", 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, "35", 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 required property, "FLOW_GRADIENT", in ["CHROMATOGRAPHY"] is missing.
Error: The ["MS_METABOLITE_DATA"]["Metabolites"] table does not have a column for "Metabolite". It is likely misspelled or using a common incorrect substitute.
