Warning: The "NIST Theo. Mol. Mass" column at position 4 in the METABOLITES table, matches a standard column name, "mass". 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 "NIST Lib Hit Formula" column at position 3 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 "NIST Lib Hit Formula" column at position 3 in the METABOLITES table, matches a standard column name, "formula", and some of the values in the column do not match the expected type or format for that column. The non-matching values are:
2         C14 H37 N O Si3
6        C13 H33 N O2 Si3
7        C17 H37 N O3 Si2
8        C14 H35 N O2 Si3
10    C20 H35 F3 N2 O Si3
14       C18 H35 N O3 Si3
22       C11 H29 N O2 Si3
25       C14 H33 N O4 Si3
29       C11 H27 N O2 Si2
35        C17 H35 N O Si3
Warning: The "Pubchem CID" column at position 5 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.
