"ION_MODE" is where that should be indicated. Error: An empty value or a null value was detected in ["MS"]["MS_COMMENTS"]. Either a legitimate value should be provided for this key, or it should be removed altogether. Error: The value, "Autosampler temp 4 C", in ["CHROMATOGRAPHY"]["TARGET_SAMPLE_TEMPERATURE"] should be a number 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 "PubChem ID" 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 "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 Time" 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. Warning: The "KEGG ID" column at position 4 in the ["MS_METABOLITE_DATA"]["Metabolites"] table has all null values. Warning: The "PubChem ID" column at position 5 in the ["MS_METABOLITE_DATA"]["Metabolites"] table has all null values.
