Warning: The "chemical formula" column at position 2 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 "Pubchem id" column at position 3 in the METABOLITES table, matches a standard column name, "pubchem_id", and some of the values in the column do not match the expected type or format for that column.

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 METABOLITES table, but this column implies that another column, "retention_index_type", should also exist, and that column was not found.
