"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.

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.
