A legitimate value should be provided for this required subsection. Error: The value 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_A", in the "CHROMATOGRAPHY" section. A legitimate value should be provided for this required subsection. 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: Unknown or invalid section, "FACTORS". Warning: The "feature (m/z@RT)" 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 "feature (m/z@RT)" column at position 3 in the METABOLITES table, matches a standard column name, "moverz_quant", and some of the values in the column do not match the expected type or format for that column.
