Ex. "PR001405". Error: An empty value or a null value was detected for the subsection, "MS_COMMENTS", in the "MS" section. Either a legitimate value should be provided for this subsection, or it should be removed altogether. Error: The required property, "FLOW_GRADIENT", in the "CHROMATOGRAPHY" section is missing. Error: The required property, "FLOW_RATE", in the "CHROMATOGRAPHY" section is missing. Error: The required property, "COLUMN_TEMPERATURE", in the "CHROMATOGRAPHY" section is missing. Error: The required property, "SOLVENT_A", in the "CHROMATOGRAPHY" section is missing. Error: The required property, "SOLVENT_B", in the "CHROMATOGRAPHY" section is missing. Warning: The "quantified m/z" column at position 2 in the 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 "InChIKey" column at position 10 in the METABOLITES table, matches a standard column name, "inchi_key". 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 "chemical_formula" column at position 6 in the METABOLITES table, matches a standard column name, "formula". 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 3 in the 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 4 in the 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" column at position 9 in the 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 "database_identifier" column at position 5 in the METABOLITES table, matches a standard column name, "other_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 column "database_identifier" was found in the METABOLITES table, but this column implies that another column, "other_id_type", should also exist, and that column was not found. Warning: The standard column, "other_id", was found in the METABOLITES table as "database_identifier". If this column contains database IDs for standard databases such as KEGG, PubChem, HMDB, etc., it is recommended to make individual columns for these and not lump them together into a less descriptive "other_id" column.
