Issue Log:
Error: The value, "20–25 g", 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"]["HEIGHT_OR_HEIGHT_RANGE"] should be a number or range (ex. "5-6") followed by a space with a unit (ex. "5 V") from the following list: ['cm', 'in']. Ignore this when more complicated descriptions are required.
Error: An empty value or a null value was detected in ["COLLECTION"]["COLLECTION_PROTOCOL_FILENAME"]. 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 ["COLLECTION"]["ADDITIVES"]. 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 ["TREATMENT"]["TREATMENT_PROTOCOL_FILENAME"]. Either a legitimate value should be provided for this key, or it should be removed altogether.
Error: The value, "16 weeks, once daily", in ["TREATMENT"]["TREATMENT_DOSEDURATION"] should be a number or range (ex. "5-6") followed by a space with a unit (ex. "5 V") from the following list: ['h', 'weeks', 'days']. Ignore this when more complicated descriptions are required.
Error: An empty value or a null value was detected in ["TREATMENT"]["ANIMAL_VET_TREATMENTS"]. 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"]["SAMPLEPREP_PROTOCOL_FILENAME"]. 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_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"]["SAMPLE_DERIVATIZATION"]. Either a legitimate value should be provided for this key, or it should be removed altogether.
Error: The value, "0.25 mL/min", in ["CHROMATOGRAPHY"]["FLOW_RATE"] 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, "40", 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, "2 µL partial‑loop", 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, "~8000 psi", in ["CHROMATOGRAPHY"]["COLUMN_PRESSURE"] should be a number or range (ex. "5-6") followed by a space with a unit (ex. "5 V") from the following list: ['psi', 'bar']. Ignore this when more complicated descriptions are required.
Error: The value, "8", in ["CHROMATOGRAPHY"]["INJECTION_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'] or "room temperature". Ignore this when more complicated descriptions are required.
Error: The value, "21 min total", 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, "3.5 kV (positive mode) / −2.8 kV (negative mode)", 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 value, "280", in ["CHROMATOGRAPHY"]["TRANSFERLINE_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.
