A legitimate value should be provided for this required subsection. Error: The value, "300ul/min", for the subsection, "FLOW_RATE", in the "CHROMATOGRAPHY" section 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", for the subsection, "COLUMN_TEMPERATURE", in the "CHROMATOGRAPHY" section 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: SUBJECT_SAMPLE_FACTORS entry #1 has the following duplicate keys in its Additional sample data: "RAW_FILE_NAME" "RAW_FILE_NAME" "RAW_FILE_NAME" "RAW_FILE_NAME" Warning: SUBJECT_SAMPLE_FACTORS entry #2 has the following duplicate keys in its Additional sample data: "RAW_FILE_NAME" "RAW_FILE_NAME" "RAW_FILE_NAME" "RAW_FILE_NAME" Warning: SUBJECT_SAMPLE_FACTORS entry #3 has the following duplicate keys in its Additional sample data: "RAW_FILE_NAME" "RAW_FILE_NAME" "RAW_FILE_NAME" "RAW_FILE_NAME" Warning: SUBJECT_SAMPLE_FACTORS entry #4 has the following duplicate keys in its Additional sample data: "RAW_FILE_NAME" "RAW_FILE_NAME" "RAW_FILE_NAME" "RAW_FILE_NAME" Warning: SUBJECT_SAMPLE_FACTORS entry #5 has the following duplicate keys in its Additional sample data: "RAW_FILE_NAME" "RAW_FILE_NAME" "RAW_FILE_NAME" "RAW_FILE_NAME" Warning: SUBJECT_SAMPLE_FACTORS entry #6 has the following duplicate keys in its Additional sample data: "RAW_FILE_NAME" "RAW_FILE_NAME" "RAW_FILE_NAME" "RAW_FILE_NAME" Warning: SUBJECT_SAMPLE_FACTORS entry #7 has the following duplicate keys in its Additional sample data: "RAW_FILE_NAME" "RAW_FILE_NAME" "RAW_FILE_NAME" "RAW_FILE_NAME" Warning: SUBJECT_SAMPLE_FACTORS entry #8 has the following duplicate keys in its Additional sample data: "RAW_FILE_NAME" "RAW_FILE_NAME" "RAW_FILE_NAME" "RAW_FILE_NAME" Warning: SUBJECT_SAMPLE_FACTORS entry #9 has the following duplicate keys in its Additional sample data: "RAW_FILE_NAME" "RAW_FILE_NAME" "RAW_FILE_NAME" "RAW_FILE_NAME" Warning: SUBJECT_SAMPLE_FACTORS entry #10 has the following duplicate keys in its Additional sample data: "RAW_FILE_NAME" "RAW_FILE_NAME" "RAW_FILE_NAME" "RAW_FILE_NAME" Warning: The "ri" column at position 7 in the 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 "ri_type" column at position 8 in the METABOLITES table, matches a standard column name, "retention_index_type". 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 pair, "ri" and "ri_type", in the METABOLITES table should have data in the same rows, but at least one row has data in one column and nothing in the other. Warning: The standard column, "other_id", was found in the METABOLITES table as "other_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. Warning: The "pubchem_id" column at position 2 in the METABOLITES table has all null values. Warning: The "inchi_key" column at position 3 in the METABOLITES table has all null values. Warning: The "kegg_id" column at position 4 in the METABOLITES table has all null values. Warning: The "other_id" column at position 5 in the METABOLITES table has all null values. Warning: The "other_id_type" column at position 6 in the METABOLITES table has all null values. Warning: The "ri_type" column at position 8 in the METABOLITES table has all null values. Warning: The "moverz_quant" column at position 9 in the METABOLITES table has all null values.
