Error: The value, "3kV", in ["MS"]["SPRAY_VOLTAGE"] 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 in ["MS_METABOLITE_DATA"]["Units"]. A legitimate value should be provided for this required key.
Error: The value, "40C", 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.
Warning: The "Metabolite" column at position 1 in the ["MS_METABOLITE_DATA"]["Data"] table has all null values.
Warning: The "5p" column at position 2 in the ["MS_METABOLITE_DATA"]["Data"] table has all null values.
Warning: The "95p" column at position 3 in the ["MS_METABOLITE_DATA"]["Data"] table has all null values.
Warning: The "Blank" column at position 4 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.
