Issue Log:
Error: The value, "Male and female", 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 ["TREATMENT"]["HUMAN_ENDP_CLINICAL_SIGNS"]. 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"]["PROCESSING_METHOD"]. 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_RESUSPENSION"]. 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_SPIKING"]. Either a legitimate value should be provided for this key, or it should be removed altogether.
Error: The required property, "ANALYSIS_TYPE", in ["ANALYSIS"] is missing.

Error: An empty value or a null value was detected in ["NM"]["CHEMICAL_SHIFT_REF_CPD"]. Either a legitimate value should be provided for this key, or it should be removed altogether.
Error: The value, "4 oC", in ["NM"]["TEMPERATURE"] should be a number followed by a space with a unit (ex. "5 V") from the following list: ['°C', 'C', 'K']. Ignore this when more complicated descriptions are required.
Error: The value, "16384 points", in ["NM"]["NUM_DATA_POINTS_ACQUIRED"] should be a unitless number. Ignore this when more complicated descriptions are required.
Error: The ["NMR_METABOLITE_DATA"]["Metabolites"] table does not have a column for "Metabolite". It is likely misspelled or using a common incorrect substitute.
