"5-6") followed by a space with a unit (ex. "5 V") from the following list: ['weeks', 'days', 'months', 'years']. Ignore this when more complicated descriptions are required. Error: An empty value or a null value was detected in ["CHROMATOGRAPHY"]["FLOW_GRADIENT"]. A legitimate value should be provided for this required key. You may have to ignore this error in certain situations. For example, SOLVENT_A for a GCMS experiment. Error: The value in ["CHROMATOGRAPHY"]["COLUMN_TEMPERATURE"] should be a number or range (ex.

Error: SUBJECT_SAMPLE_FACTORS section missing sample ID(s). The following IDs were found in the ["MS_METABOLITE_DATA"]["Data"] section but not in the SUBJECT_SAMPLE_FACTORS: "" Warning: The "m/z" column at position 2 in the ["MS_METABOLITE_DATA"]["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.
