Issue Log:
Error: An empty value or a null value was detected in ["CHROMATOGRAPHY"]["FLOW_GRADIENT"]. A legitimate value should be provided for this required key.
Error: The value, "-", in ["CHROMATOGRAPHY"]["FLOW_RATE"] 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 in ["CHROMATOGRAPHY"]["COLUMN_TEMPERATURE"] 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 in ["CHROMATOGRAPHY"]["SOLVENT_A"]. A legitimate value should be provided for this required key.
Error: An empty value or a null value was detected in ["CHROMATOGRAPHY"]["SOLVENT_B"]. A legitimate value should be provided for this required key.
Warning: The "MOL. WEIGHT" column at position 2 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 "MOL. WEIGHT" column at position 2 in the ["MS_METABOLITE_DATA"]["Metabolites"] table, matches a standard column name, "mass", and some of the values in the column do not match the expected type or format for that column. The non-matching values are:
9    †89
Warning: The "RETENTION TIME" column at position 3 in the ["MS_METABOLITE_DATA"]["Metabolites"] table, matches a standard column name, "retention_time". 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.
