Issue Log:
Error: The required property, "COLLECTION_SUMMARY", in ["COLLECTION"] is missing.
Error: An empty value or a null value was detected in ["TREATMENT"]["TREATMENT_SUMMARY"]. A legitimate value should be provided for this required key.
Error: The value, "0.45 ml/min", 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, "55C", 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.
Warning: The "mz" column at position 3 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.
Warning: The "neutral_mass" column at position 4 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 "formula" column at position 2 in the ["MS_METABOLITE_DATA"]["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. The non-matching values are:
3         C3 H7 N O3
5         C4 H9 N O3
6       C2 H7 N O3 S
9         C4 H7 N O4

68    C26 H45 N O7 S
Warning: The "refmet_name" column at position 5 in the ["MS_METABOLITE_DATA"]["Metabolites"] table, matches a standard column name, "name". 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 "rt" column at position 6 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.
