Warning: The "quant mz" column at position 4 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 "PubChem" column at position 2 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" column at position 2 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 "ret.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. Error: Column(s) with no name were found in the METABOLITES table. Error: The section, METABOLITES, has a mismatch between the number of headers and the number of elements in each line. Either a line(s) has more values than headers or there are too few headers.
