A legitimate value should be provided for this required subsection. Error: An empty value or a null value was detected for the subsection, "FLOW_GRADIENT", in the "CHROMATOGRAPHY" section. A legitimate value should be provided for this required subsection. Error: The value, "10 µl/min", for the subsection, "FLOW_RATE", 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: ['mL/min', 'uL/min', 'μL/min']. Ignore this when more complicated descriptions are required. Error: The value, "none", 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: An empty value or a null value was detected for the subsection, "SOLVENT_B", in the "CHROMATOGRAPHY" section. A legitimate value should be provided for this required subsection. Error: The value, "260", for the subsection, "INJECTION_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'] or "room temperature". Ignore this when more complicated descriptions are required. Warning: The "SuperClass" column at position 3 in the METABOLITES table, matches a standard column name, "class". 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 "CLASS_2" column at position 12 in the METABOLITES table, matches a standard column name, "class". 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 "SuperClass" column at position 3 in the METABOLITES table, matches a standard column name, "class", and some of the values in the column do not match the expected type or format for that column. The non-matching values are: 233 PCHO 234 PCHO 235 PCHO 236 PCHO 237 PCHO 238 PCHO 239 PCHO 240 PCHO 241 PCHO 242 PCHO 243 PCHO 244 PCHO 245 PCHO 246 PCHO 247 PCHO 248 PCHO 249 PCHO 250 PCHO 251 PCHO 252 PCHO 253 PCHO 254 PCHO 255 PCHO 256 PCHO 257 PCHO 258 PCHO 259 PCHO 260 PCHO 261 PCHO 262 PCHO 263 PCHO 264 PCHO 265 PCHO 266 PCHO Warning: The "CLASS_2" column at position 12 in the METABOLITES table, matches a standard column name, "class", and some of the values in the column do not match the expected type or format for that column.
