Issue Log:
Error: The value, "20-30 gram", in ["SUBJECT"]["WEIGHT_OR_WEIGHT_RANGE"] should be a number or range (ex. "5-6") followed by a space with a unit (ex. "5 V") from the following list: ['g', 'mg', 'kg', 'lbs']. Ignore this when more complicated descriptions are required.
Error: An empty value or a null value was detected in ["TREATMENT"]["TREATMENT_VEHICLE"]. Either a legitimate value should be provided for this key, or it should be removed altogether.
Error: An empty value or a null value was detected in ["TREATMENT"]["ANIMAL_VET_TREATMENTS"]. Either a legitimate value should be provided for this key, or it should be removed altogether.
Error: The value, "0.4ml/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, "25", 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 "KEGG ID" column at position 7 in the ["MS_METABOLITE_DATA"]["Metabolites"] table, matches a standard column name, "kegg_id". 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 "CAS ID" column at position 5 in the ["MS_METABOLITE_DATA"]["Metabolites"] table, matches a standard column name, "cas_number". 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 "Retention times" 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.
