Issue Log:
Error: The value, "18-65", in ["SUBJECT"]["AGE_OR_AGE_RANGE"] should be a number or range (ex. "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: The value, "55", 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 "Exact 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 "Metabolite name" column at position 2 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 "PubChem CID" column at position 5 in the ["MS_METABOLITE_DATA"]["Metabolites"] table, matches a standard column name, "pubchem_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 "230707_15-LOX_M2-Homogenat_STP_2" column at position 3 in the ["MS_METABOLITE_DATA"]["Data"] table has all null values.
Warning: The "230707_15-LOX_M2-Homogenat_STP_7" column at position 8 in the ["MS_METABOLITE_DATA"]["Data"] table has all null values.
Warning: The "230707_15-LOX_M2-Homogenat_STP_16" column at position 15 in the ["MS_METABOLITE_DATA"]["Data"] table has all null values.
