A legitimate value should be provided for this required key. Error: The value, "N2", in ["MS"]["COLLISION_GAS"] should be one of "Nitrogen" or "Argon". Ignore this when more complicated descriptions are required. Error: The value, "N/A", in ["MS"]["DRY_GAS_FLOW"] should be a number followed by a space with a unit (ex. "5 V") from the following list: ['L/hr', 'L/min']. Ignore this when more complicated descriptions are required. Error: The value, "N/A", in ["MS"]["DRY_GAS_TEMP"] should be a number 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 in ["CHROMATOGRAPHY"]["INSTRUMENT_NAME"]. A legitimate value should be provided for this required key. Error: An empty value or a null value was detected in ["CHROMATOGRAPHY"]["COLUMN_NAME"]. A legitimate value should be provided for this required key. Error: The value, "300 nL/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, "60°C", 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 value, "5 µL", in ["CHROMATOGRAPHY"]["SAMPLE_INJECTION"] should be a number followed by a space with a unit (ex. "5 V") from the following list: ['μL', 'uL']. Ignore this when more complicated descriptions are required. Error: The value, "RT", in ["CHROMATOGRAPHY"]["INJECTION_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'] or "room temperature". Ignore this when more complicated descriptions are required. Error: SUBJECT_SAMPLE_FACTORS section missing sample ID(s). The following IDs were found in the ["MS_METABOLITE_DATA"]["Data"] section but not in the SUBJECT_SAMPLE_FACTORS: "" Error: Column(s) with no name were found in the ["MS_METABOLITE_DATA"]["Data"] table. Warning: The "" column at position 31 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.
