Warning: The "CHRO_LIB_ENTRY_ID" 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 "CHEM_ID" 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 "CHEM_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 "LIPID SPECIES LEVEL" column at position 13 in the METABOLITES table may have incorrect values. 90% or more of the values are the same, but 10% or less are different. Warning: The "LIPID MOLECULAR SPECIES LEVEL" column at position 14 in the METABOLITES table may have incorrect values. 90% or more of the values are the same, but 10% or less are different. Warning: The "LIPID SN POSITION LEVEL" column at position 15 in the METABOLITES table may have incorrect values. 90% or more of the values are the same, but 10% or less are different.
