Issue Log:
Error: The value, "56-78", for the subsection, "AGE_OR_AGE_RANGE", in the "SUBJECT" section 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, "Obese or Overweight", for the subsection, "WEIGHT_OR_WEIGHT_RANGE", in the "SUBJECT" section 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: An empty value or a null value was detected for the subsection, "TREATMENT_SUMMARY", in the "TREATMENT" section. A legitimate value should be provided for this required subsection.
Error: An empty value or a null value was detected for the subsection, "EXTRACTION_METHOD", in the "SAMPLEPREP" section. Either a legitimate value should be provided for this subsection, or it should be removed altogether.
Error: The value, "12.589w", for the subsection, "POWER_LEVEL", in the "NM" section 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, "0.865 sec", for the subsection, "ACQUISITION_TIME", in the "NM" section should be a number followed by a space with a unit (ex. "5 V") from the following list: ['s']. Ignore this when more complicated descriptions are required.
Error: The value, "2 sec", for the subsection, "RELAXATION_DELAY", in the "NM" section should be a number followed by a space with a unit (ex. "5 V") from the following list: ['s', 'ms', 'us', 'μs']. Ignore this when more complicated descriptions are required.
Error: The value, "32K", for the subsection, "NUM_DATA_POINTS_ACQUIRED", in the "NM" section should be a unitless number. Ignore this when more complicated descriptions are required.
Error: The value, "0.5", for the subsection, "LINE_BROADENING", in the "NM" section should be a number followed by a space with a unit (ex. "5 V") from the following list: ['Hz']. Ignore this when more complicated descriptions are required.
Error: An empty value or a null value was detected for the subsection, "Units", in the "NMR_METABOLITE_DATA" section. A legitimate value should be provided for this required subsection.
Error: Unknown or invalid section, "CHROMATOGRAPHY".
Warning: The "Metabolite" column at position 1 in the NMR_METABOLITE_DATA table has all null values.
Warning: The "1338-fu18" column at position 2 in the NMR_METABOLITE_DATA table has all null values.
Warning: The "Metabolite" column at position 1 in the METABOLITES table has all null values.
