Either a legitimate value should be provided for this key, or it should be removed altogether. Error: The required property, "FLOW_GRADIENT", in ["CHROMATOGRAPHY"] is missing. Error: The required property, "FLOW_RATE", in ["CHROMATOGRAPHY"] is missing. Error: The required property, "COLUMN_TEMPERATURE", in ["CHROMATOGRAPHY"] is missing. Warning: The "quantified m/z" column at position 3 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 "Study Metabolite Name" column at position 7 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 ID" column at position 4 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 ID" column at position 5 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 "HMDB ID" column at position 6 in the ["MS_METABOLITE_DATA"]["Metabolites"] table, matches a standard column name, "hmdb_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 time" column at position 2 in the ["MS_METABOLITE_DATA"]["Metabolites"] table, matches a standard column name, "retention_time". 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.
