Issue Log:
Error: An empty value or a null value was detected for the subsection, "PROJECT_COMMENTS", in the "PROJECT" section. Either a legitimate value should be provided for this subsection, or it should be removed altogether.
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, "ADDITIVES", in the "COLLECTION" section. Either a legitimate value should be provided for this subsection, or it should be removed altogether.
Error: The value, "Time (0, 6, 12, 24, 48, 96 h)", for the subsection, "TREATMENT_DOSEDURATION", in the "TREATMENT" section 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: The value, "25°C", for the subsection, "PLANT_TEMP", in the "TREATMENT" 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, "SAMPLEPREP_PROTOCOL_ID", 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, "SAMPLEPREP_PROTOCOL_FILENAME", 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, "SAMPLEPREP_PROTOCOL_COMMENTS", 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_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, "1 ml/min", for the subsection, "HELIUM_FLOW", in the "MS" section should be a number followed by a space with a unit (ex. "5 V") from the following list: ['mL/min']. Ignore this when more complicated descriptions are required.
Error: The value, "260", for the subsection, "ION_SOURCE_TEMPERATURE", in the "MS" section 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.
Error: The value, "260", for the subsection, "SOURCE_TEMPERATURE", in the "MS" section 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.
Error: Unknown or invalid subsection, "ACQUISITION_DATE", in the "MS" section .
Error: The value, "1 ml/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.
