Issue Log:
Error: An empty value or a null value was detected in ["PROJECT"]["PHONE"]. A legitimate value should be provided for this required key.
Error: An empty value or a null value was detected in ["STUDY"]["PHONE"]. A legitimate value should be provided for this required key.
Error: The value, "10 weeks and 12-24 months (young & old)", 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, "~25 g and ~34 g", in ["SUBJECT"]["WEIGHT_OR_WEIGHT_RANGE"] 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 in ["COLLECTION"]["COLLECTION_SUMMARY"]. A legitimate value should be provided for this required key.
Error: The value, "Whole blood", in ["COLLECTION"]["BLOOD_SERUM_OR_PLASMA"] should be one of "Blood", "Plasma", or "Serum". 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"]["EXTRACT_CLEANUP"]. Either a legitimate value should be provided for this key, or it should be removed altogether.
Error: The value, "10% (~0.5mM)", in ["NM"]["STANDARD_CONCENTRATION"] should be a number followed by a space with a unit (ex. "5 V") from the following list: ['mM']. Ignore this when more complicated descriptions are required.
Error: The value, "around -178Hz", in ["NM"]["OFFSET_FREQUENCY"] should be a number followed by a space with a unit (ex. "5 V") from the following list: ['ppm', 'Hz']. Ignore this when more complicated descriptions are required.
Error: The value, "25°C", 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: Unknown or invalid section, "CHROMATOGRAPHY".
Warning: The "KEGG ID" column at position 2 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.
