"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, "Sexually mature male and female frogs", for the subsection, "WEIGHT_OR_WEIGHT_RANGE", in the "SUBJECT" section should be a number or range (ex. "5-6") followed by a space with a unit (ex. "5 V") from the following list: ['g', 'mg', 'kg', 'lbs']. Ignore this when more complicated descriptions are required. Error: The value, "Not applicable", 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, "EXTRACT_ENRICHMENT", in the "SAMPLEPREP" section. Either a legitimate value should be provided for this subsection, or it should be removed altogether. Error: An empty value or a null value was detected for the subsection, "EXTRACT_CLEANUP", in the "SAMPLEPREP" section. Either a legitimate value should be provided for this subsection, or it should be removed altogether. Error: The value, "100 degC", for the subsection, "CAPILLARY_TEMPERATURE", in the "MS" 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: The value, "+1700 V during cationic analysis", for the subsection, "CAPILLARY_VOLTAGE", in the "MS" section should be a number followed by a space with a unit (ex. "5 V") from the following list: ['V', 'kV']. Ignore this when more complicated descriptions are required. Error: An empty value or a null value was detected for the subsection, "MS_COMMENTS", in the "MS" section. Either a legitimate value should be provided for this subsection, or it should be removed altogether. Error: The value, "Room temperature", 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: The value, "Ca. 10 nL", for the subsection, "SAMPLE_INJECTION", in the "CHROMATOGRAPHY" section should be a number followed by a space with a unit (ex. "5 V") from the following list: ['μL', 'uL']. Ignore this when more complicated descriptions are required. Error: The value, "45 min of separation", for the subsection, "ANALYTICAL_TIME", 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: ['min']. Ignore this when more complicated descriptions are required. Error: The value for the subsection, "CAPILLARY_VOLTAGE", in the "CHROMATOGRAPHY" section should be a number followed by a space with a unit (ex. "5 V") from the following list: ['V', 'kV']. Ignore this when more complicated descriptions are required. Error: The required property, "FLOW_GRADIENT", in the "CHROMATOGRAPHY" section is missing. Error: The required property, "FLOW_RATE", in the "CHROMATOGRAPHY" section is missing. Error: The required property, "SOLVENT_B", in the "CHROMATOGRAPHY" section is missing. Warning: The "Moverz Quant" column at position 3 in the 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 CID" column at position 5 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 "Local ID (CAS)" column at position 4 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 "Retention Index" 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 "Retention Index" 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. Warning: The "Moverz Quant" column at position 3 in the METABOLITES table has all null values. Warning: The "Local ID (CAS)" column at position 4 in the METABOLITES table has all null values.
