A legitimate value should be provided for this required subsection. Error: The value, "3kV", for the subsection, "SPRAY_VOLTAGE", in the "MS" section should be a number followed by a space with a unit (ex. "5 V") from the following list: ['kV']. 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: The value, "40C", 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: The required property, "FLOW_GRADIENT", in the "CHROMATOGRAPHY" section is missing. Warning: The "Metabolite" column at position 1 in the MS_METABOLITE_DATA table has all null values.
