A legitimate value should be provided for this required key. Error: The value, "1.52mL/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 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: An empty value or a null value was detected in ["CHROMATOGRAPHY"]["SOLVENT_A"]. A legitimate value should be provided for this required key. Error: An empty value or a null value was detected in ["CHROMATOGRAPHY"]["SOLVENT_B"]. A legitimate value should be provided for this required key. Warning: The "Characteristic_m/z" column at position 6 in the ["MS_METABOLITE_DATA"]["Metabolites"] table, matches a standard column name, "moverz_quant". If this match was not in error, the column should be renamed to the standard name or a name that doesn't resemble the standard name. Warning: The "Characteristic_m/z" column at position 6 in the ["MS_METABOLITE_DATA"]["Metabolites"] table, matches a standard column name, "moverz_quant", and some of the values in the column do not match the expected type or format for that column. The non-matching values are: 5 sum 14 sum 19 sum 30 sum 54 sum 64 sum 76 sum 77 sum 78 sum 84 sum 86 sum 106 sum 110 sum 119 sum 219 2803.7/204(479) 228 2932.3/204(479) 230 2974.4/204(479) Warning: The "Samplename" column at position 2 in the ["MS_METABOLITE_DATA"]["Metabolites"] table, matches a standard column name, "name". If this match was not in error, the column should be renamed to the standard name or a name that doesn't resemble the standard name. Warning: The "PubChem" column at position 3 in the ["MS_METABOLITE_DATA"]["Metabolites"] table, matches a standard column name, "pubchem_id". If this match was not in error, the column should be renamed to the standard name or a name that doesn't resemble the standard name. Warning: The "KEGG" column at position 4 in the ["MS_METABOLITE_DATA"]["Metabolites"] table, matches a standard column name, "kegg_id". If this match was not in error, the column should be renamed to the standard name or a name that doesn't resemble the standard name. Warning: The "Retention Index" column at position 5 in the ["MS_METABOLITE_DATA"]["Metabolites"] table, matches a standard column name, "retention_index". If this match was not in error, the column should be renamed to the standard name or a name that doesn't resemble the standard name. Warning: The "Mode" column at position 8 in the ["MS_METABOLITE_DATA"]["Metabolites"] table, matches a standard column name, "ionization_mode". If this match was not in error, the column should be renamed to the standard name or a name that doesn't resemble the standard name. Warning: The "Mode" column at position 8 in the ["MS_METABOLITE_DATA"]["Metabolites"] table, matches a standard column name, "ionization_mode", and some of the values in the column do not match the expected type or format for that column. The non-matching values are: 11 S60 13 SplitlessFLAVOS 24 SplitlessFLAVOS 28 S60 29 S60 33 S60 41 SplitlessFLAVOS 58 S60 60 S60 61 S60 78 S60 80 S60 83 S60 89 S60 99 S60 104 SplitlessFLAVOS 107 S60 112 S60 123 S120 124 SplitlessFLAVOS 162 Splitlessspe 172 Splitlessspe 181 S60 216 S60 218 SplitlessFLAVOS 222 S120 223 S60 224 S120 225 S60 226 Splitlessspe 242 SplitlessFLAVOS Warning: The column "Retention Index" was found in the ["MS_METABOLITE_DATA"]["Metabolites"] table, but this column implies that another column, "retention_index_type", should also exist, and that column was not found.
