Issue Log:
Error: An empty value or a null value was detected in ["COLLECTION"]["ADDITIVES"]. Either a legitimate value should be provided for this key, or it should be removed altogether.
Error: The value, "450 µL/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, "45°C", 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 "Study_Compound_ID" column at position 2 in the ["MS_METABOLITE_DATA"]["Metabolites"] table, matches a standard column name, "other_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 "RT" column at position 4 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.
Warning: The column "Study_Compound_ID" was found in the ["MS_METABOLITE_DATA"]["Metabolites"] table, but this column implies that another column, "other_id_type", should also exist, and that column was not found.
Warning: The standard column, "other_id", was found in the METABOLITES table as "Study_Compound_ID". If this column contains database IDs for standard databases such as KEGG, PubChem, HMDB, etc., it is recommended to make individual columns for these and not lump them together into a less descriptive "other_id" column.
