"5-6") followed by a space with a unit (ex. "5 V") from the following list: ['mL/min', 'uL/min', 'μL/min']. Ignore this when more complicated descriptions are required. Error: The value, "40", for the subsection, "COLUMN_TEMPERATURE", in the "CHROMATOGRAPHY" section should be a number or range (ex. "5-6") followed by a space with a unit (ex. "5 V") from the following list: ['°C', 'C']. Ignore this when more complicated descriptions are required. Error: SUBJECT_SAMPLE_FACTORS section missing sample ID(s). The following IDs were found in the MS_METABOLITE_DATA section but not in the SUBJECT_SAMPLE_FACTORS: "" Warning: There are duplicate samples in the MS_METABOLITE_DATA section. Warning: The "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 "Formula" column at position 2 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 H16 N O11 P 3 C7 H11 N O4 7 C51 H77 N O2 8 C45 H75 N O10 11 C9 H15 N O4 12 C29 H59 N O3 13 C46 H77 N O7 19 C28 H49 N O6 32 C19 H40 N2 O P2 51 C5 H2 O S2 56 C22 H43 N O 68 C18 H19 Br Cl N O2 70 C28 H53 N O6 71 C17 H16 O S 73 C10 H21 N O5 77 C5 H9 N5 O S 83 C51 H63 Cl N2 O11 S 86 C8 H13 N O4 88 C27 H28 N O10 P 91 C8 H9 N O 93 C6 H11 N O4 98 C4 H3 F O3 103 C3 H5 N O2 S 109 C28 H51 N O6 117 C4 [13]C H9 N O2 119 C44 H71 N O7 120 C12 H21 N O2 S2 125 C6 H5 Cl N4 O3 129 C9 H5 Cl O3 S 135 C33 H47 N O4 138 C25 H47 N O9 140 C43 H77 N O10 141 C6 H11 N O4 149 C14 H14 O S 153 C31 H63 N O3 154 C35 H69 N O3 158 C10 H18 O S 174 C44 H79 N O7 181 F2 O Si 187 C31 H23 N O5 S 189 C8 H10 Cl P 193 C8 H20 N O6 P 202 C7 H11 N O2 204 C18 H33 N O 206 C5 H7 N O3 207 C26 H50 N O7 P 208 C24 H50 N O7 P 209 C26 H48 N O7 P 210 C23 H46 N O7 P 211 C23 H44 N O7 P 217 C26 H51 N O6 224 C19 H39 N O4 230 C27 H55 N O4 241 C27 H39 N O3 242 C20 H39 N O 243 C7 H15 N O4 247 C34 H67 N O3 251 C8 H13 N O6 253 C42 H74 N O8 P 254 C40 H70 N O8 P 255 C44 H74 N O8 P 256 C41 H76 N O8 P 257 C41 H76 N O8 P 263 C5 H14 N O4 P 274 C11 H17 N O7 285 C2 H N3 O2 289 C29 H57 N O3 Warning: The "RT [min]" column at position 4 in the METABOLITES table, matches a standard column name, "retention_time". 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. Error: Column(s) with no name were found in the MS_METABOLITE_DATA table. Error: The section, MS_METABOLITE_DATA, 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.
