Issue Log:
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: The required property, "ANALYSIS_TYPE", in ["ANALYSIS"] is missing.
Error: The value, "12.3 Watts", 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, "0.0000964 Watts", 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, "3.9 seconds", 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, "2 seconds", 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, "0.04ppm", in ["NM"]["BINNED_INCREMENT"] should be a number followed by a space with a unit (ex. "5 V") from the following list: ['ppm']. Ignore this when more complicated descriptions are required.
Warning: The "PubChem Compound" column at position 5 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 Compound ID" 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 Accession Number" column at position 3 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.
Warning: The "CAS Registry" column at position 2 in the ["NMR_METABOLITE_DATA"]["Metabolites"] table, matches a standard column name, "cas_number". 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.
