Issue Log:
Error: An empty value or a null value was detected in ["SUBJECT_SAMPLE_FACTORS"][54]["Sample ID"]. A legitimate value should be provided for this required key.
Error: The value, "flow rate of 150 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, "40", 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 "quantified m/z" column at position 2 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 "KEGG ID" column at position 4 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 "retention index" column at position 3 in the ["MS_METABOLITE_DATA"]["Metabolites"] table, matches a standard column name, "retention_index". 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 "retention index" was found in the ["MS_METABOLITE_DATA"]["Metabolites"] table, but this column implies that another column, "retention_index_type", should also exist, and that column was not found.
