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. Error: The required property, "SOLVENT_A", in ["CHROMATOGRAPHY"] is missing. Error: The required property, "SOLVENT_B", in ["CHROMATOGRAPHY"] is missing. 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 2 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 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.
