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 "ri_type" column at position 8 in the METABOLITES table, matches a standard column name, "retention_index_type". 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 standard column, "other_id", was found in the METABOLITES table as "other_id". 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. Warning: The "inchi_key" column at position 3 in the METABOLITES table has all null values. Warning: The "kegg_id" column at position 4 in the METABOLITES table has all null values. Warning: The "other_id" column at position 5 in the METABOLITES table has all null values. Warning: The "other_id_type" column at position 6 in the METABOLITES table has all null values. Warning: The "ri" column at position 7 in the METABOLITES table has all null values. Warning: The "ri_type" column at position 8 in the METABOLITES table has all null values. Warning: The "moverz_quant" column at position 9 in the METABOLITES table has all null values.
