Issue Log:
Error: An empty value or a null value was detected in ["PROJECT"]["FUNDING_SOURCE"]. 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 ["PROJECT"]["PROJECT_COMMENTS"]. 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 ["STUDY"]["STUDY_COMMENTS"]. Either a legitimate value should be provided for this key, or it should be removed altogether.
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 ["COLLECTION"]["COLLECTION_METHOD"]. Either a legitimate value should be provided for this key, or it should be removed altogether.
Error: The value, "63", in ["NM"]["POWER_LEVEL"] should be a number followed by a space with a unit (ex. "5 V") from the following list: ['W', 'dB']. Ignore this when more complicated descriptions are required.
Error: The value, "20", in ["NM"]["PRESATURATION_POWER_LEVEL"] should be a number followed by a space with a unit (ex. "5 V") from the following list: ['W', 'dB']. Ignore this when more complicated descriptions are required.
Error: The value, "25", 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.
