"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, "Male and female", for the subsection, "GENDER", in the "SUBJECT" section should be one of "Male", "Female", "Male, Female", "Hermaphrodite", or "N/A". Ignore this when more complicated descriptions are required. Error: An empty value or a null value was detected for the subsection, "FLOW_GRADIENT", in the "CHROMATOGRAPHY" section. A legitimate value should be provided for this required subsection. Error: The value, "-", 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, "-", 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. Error: An empty value or a null value was detected for the subsection, "SOLVENT_A", in the "CHROMATOGRAPHY" section. A legitimate value should be provided for this required subsection. Error: An empty value or a null value was detected for the subsection, "SOLVENT_B", in the "CHROMATOGRAPHY" section. A legitimate value should be provided for this required subsection. Error: Unknown or invalid section, "FACTORS". Warning: The "PUBCHEM" column at position 4 in the 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" column at position 6 in the 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 "CAS" column at position 5 in the METABOLITES table, matches a standard column name, "cas_number". 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 "CAS" column at position 5 in the METABOLITES table, matches a standard column name, "cas_number", and some of the values in the column do not match the expected type or format for that column. The non-matching values are: 44 26853-31-6;26853-31-6 65 59-02-9;10191-41-0 74 55482-27-4;55482-27-4 175 85187-10-6;85187-10-6 Warning: The "RI" column at position 2 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 column "RI" was found in the METABOLITES table, but this column implies that another column, "retention_index_type", should also exist, and that column was not found.
