A legitimate value should be provided for this required key. 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 "PubChem" column at position 2 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 3 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 6 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 5 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 5 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: 32 Splitless flavos 33 Splitless specific 34 Splitless flavos 35 Splitless specific 37 Splitless flavos 48 Splitless flavos 59 S10 63 Splitless flavos 70 Splitless flavos 77 S10 78 Splitless specific 80 S10 81 Splitless specific 82 S10 83 Splitless specific 87 Splitless specific 88 S10 90 S10 91 Splitless specific 94 Splitless specific 104 S10 121 S10 133 S10 142 S10 155 S10 159 S10 168 Splitless specific 173 Splitless specific 175 Splitless specific 215 S10 227 S10 233 S10 242 Splitless specific 250 Splitless specific 265 Splitless specific 268 Splitless specific 277 Splitless flavos 281 Splitless flavos 286 Splitless specific 287 Splitless specific 295 Splitless specific 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.
