"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. Warning: The "Molecular Weight" column at position 3 in the ["MS_METABOLITE_DATA"]["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 "Formula" column at position 2 in the ["MS_METABOLITE_DATA"]["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: 4 C10 H19 N O8 6 C4 H7 N O2 7 C4 H7 N O2 9 C25 H45 N O13 11 C3 H9 N O7 S 18 C H3 N2 O10 P 36 C5 H13 N O2 44 C H2 N7 O2 P 45 C18 H26 N2 O P2 48 C10 H19 N8 O5 P S 55 C3 H12 N P3 58 C6 H5 N O3 P2 S 61 C25 H53 N O10 64 C9 H21 N2 O P3 74 C24 H33 N O6 82 C36 H65 N O2 84 C10 H19 N O7 85 C11 H19 N O7 86 C11 H23 N O2 96 C8 H15 N O6 103 C7 H11 N O 105 C9 H9 N O4 109 C6 H11 N O4 118 C6 H11 N O3 119 C6 H11 N O3 126 C6 H9 N O3 127 C6 H9 N O3 128 C4 H7 N O3 133 C6 H14 N O8 P 134 C5 H9 N O3 135 C7 H13 N O4 138 C5 H11 N O2 139 C6 H13 N O4 141 C16 H29 N O5 142 C16 H29 N O5 144 C6 H11 N O 147 C5 H13 N O 151 C4 H11 N O 152 C2 H3 N O2 153 C6 H13 N O5 157 C3 H7 N O2 169 C6 H9 N O2 171 C6 H11 N O5 176 C6 H13 N O5 177 C6 H13 N O5 178 C3 H7 N O3 179 C3 H7 N O2 180 C4 H7 N O4 182 C4 H7 N O4 186 C5 H9 N O4 189 C5 H9 N O2 190 C5 H7 N O3 191 C5 H7 N O3 196 C5 H7 N O2 197 C4 H5 N O3 200 C5 H11 N O3 S 205 C8 H17 N O5 206 C9 H17 N O7 212 C6 H15 N O 216 C11 H19 N O9 221 C3 H10 N O4 P 222 C3 H10 N O4 P 226 C20 H24 F N3 O4 227 C7 H11 N O4 242 C5 H9 N O2 250 C9 H13 N O5 253 C4 H9 N O3 256 C4 H7 N O2 S 257 C6 H15 N O3 259 C9 H21 N O3 260 C6 H9 N O3 261 C6 H15 N O2 262 C6 H15 N O2 268 C13 H19 N O3 269 C4 H9 N O2 Warning: The "Retention times [min]" column at position 4 in the ["MS_METABOLITE_DATA"]["Metabolites"] table, matches a standard column name, "retention_time".
