Issue Log:
Error: The value, "1-18", in ["SUBJECT"]["AGE_OR_AGE_RANGE"] 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, "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"]["TREATMENT_SUMMARY"]. A legitimate value should be provided for this required key.
Error: An empty value or a null value was detected in ["SAMPLEPREP"]["EXTRACTION_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"]["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"]["EXTRACT_CLEANUP"]. 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: The value, "4s", in ["NM"]["ACQUISITION_TIME"] 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, "4s", in ["NM"]["RELAXATION_DELAY"] 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, "0,3 Hz", in ["NM"]["LINE_BROADENING"] 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: SUBJECT_SAMPLE_FACTORS section missing sample ID(s). The following IDs were found in the ["NMR_METABOLITE_DATA"]["Data"] section but not in the SUBJECT_SAMPLE_FACTORS:
	""
Warning: The "PubChem" column at position 3 in the ["NMR_METABOLITE_DATA"]["Metabolites"] table, matches a standard column name, "pubchem_id". If this match was not in error, the column should be renamed to the standard name or a name that doesn't resemble the standard name.
Warning: The "KEGG" column at position 4 in the ["NMR_METABOLITE_DATA"]["Metabolites"] table, matches a standard column name, "kegg_id". If this match was not in error, the column should be renamed to the standard name or a name that doesn't resemble the standard name.
Warning: The "HMDB ID" column at position 2 in the ["NMR_METABOLITE_DATA"]["Metabolites"] table, matches a standard column name, "hmdb_id". If this match was not in error, the column should be renamed to the standard name or a name that doesn't resemble the standard name.
Error: Column(s) with no name were found in the ["NMR_METABOLITE_DATA"]["Data"] table.
Warning: The "Level of confidence3" column at position 6 in the ["NMR_METABOLITE_DATA"]["Metabolites"] table may have incorrect values. 90% or more of the values are the same, but 10% or less are different.
