Issue Log:
Error: The value, "1 month", for the subsection, "AGE_OR_AGE_RANGE", in the "SUBJECT" section 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: An empty value or a null value was detected for the subsection, "Units", in the "MS_METABOLITE_DATA" section. A legitimate value should be provided for this required subsection.
Error: An empty value or a null value was detected for the subsection, "INSTRUMENT_NAME", in the "CHROMATOGRAPHY" section. A legitimate value should be provided for this required subsection.
Error: An empty value or a null value was detected for the subsection, "COLUMN_NAME", in the "CHROMATOGRAPHY" section. A legitimate value should be provided for this required subsection.
Error: An empty value or a null value was detected for the subsection, "FLOW_GRADIENT", in the "CHROMATOGRAPHY" section. A legitimate value should be provided for this required subsection.
Error: The value, "none", for the subsection, "FLOW_RATE", in the "CHROMATOGRAPHY" section 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, "none", for the subsection, "COLUMN_TEMPERATURE", in the "CHROMATOGRAPHY" section 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 for the subsection, "SOLVENT_A", in the "CHROMATOGRAPHY" section. A legitimate value should be provided for this required subsection.
Error: An empty value or a null value was detected for the subsection, "SOLVENT_B", in the "CHROMATOGRAPHY" section. A legitimate value should be provided for this required subsection.
