Issue Log:
Error: The value in ["SUBJECT"]["AGE_OR_AGE_RANGE"] should be a number or range (ex. "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", in ["SUBJECT"]["WEIGHT_OR_WEIGHT_RANGE"] 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", in ["SUBJECT"]["GENDER"] 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 in ["SAMPLEPREP"]["EXTRACT_ENRICHMENT"]. Either a legitimate value should be provided for this key, or it should be removed altogether.
Error: An empty value or a null value was detected in ["SAMPLEPREP"]["EXTRACT_CLEANUP"]. Either a legitimate value should be provided for this key, or it should be removed altogether.
Error: The value, "150 degC", in ["MS"]["CAPILLARY_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.
Error: The value, "-2100 during anionic analysis", in ["MS"]["CAPILLARY_VOLTAGE"] 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 in ["MS"]["MS_COMMENTS"]. Either a legitimate value should be provided for this key, or it should be removed altogether.
Error: The value, "Room temperature", 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.
Error: The value, "Ca. 10 nL", in ["CHROMATOGRAPHY"]["SAMPLE_INJECTION"] 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", in ["CHROMATOGRAPHY"]["ANALYTICAL_TIME"] 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 in ["CHROMATOGRAPHY"]["CAPILLARY_VOLTAGE"] 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 ["CHROMATOGRAPHY"] is missing.
Error: The required property, "FLOW_RATE", in ["CHROMATOGRAPHY"] is missing.
Error: The required property, "SOLVENT_B", in ["CHROMATOGRAPHY"] is missing.
Warning: The "Moverz Quant" column at position 3 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 CID" 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 "Local ID (CAS)" column at position 4 in the ["MS_METABOLITE_DATA"]["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 ["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.
Warning: The "Moverz Quant" column at position 3 in the ["MS_METABOLITE_DATA"]["Metabolites"] table has all null values.
Warning: The "Local ID (CAS)" column at position 4 in the ["MS_METABOLITE_DATA"]["Metabolites"] table has all null values.
