A legitimate value should be provided for this required subsection. Error: Unknown or invalid section, "CHROMATOGRAPHY". Warning: The "quantified m/z" column at position 3 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 "Common Name" column at position 6 in the METABOLITES table, matches a standard column name, "name". 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 4 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 5 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 "retention index" column at position 2 in the METABOLITES table, matches a standard column name, "retention_index". 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 "Isotope" column at position 8 in the METABOLITES table, matches a standard column name, "isotopologue_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 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. Warning: The "retention index" column at position 2 in the METABOLITES table has all null values. Warning: The "quantified m/z" column at position 3 in the METABOLITES table has all null values. Warning: The "PubChem ID" column at position 4 in the METABOLITES table has all null values. Warning: The "KEGG ID" column at position 5 in the METABOLITES table has all null values.
