Issue Log:
Error: An empty value or a null value was detected in ["PROJECT"]["ADDRESS"]. A legitimate value should be provided for this required key.
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"]["ADDRESS"]. 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, "600 MHZ", in ["NM"]["SPECTROMETER_FREQUENCY"] should be a number followed by a space with a unit (ex. "5 V") from the following list: ['MHz']. Ignore this when more complicated descriptions are required.
Error: The value, "Deuterium", 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, "0.05 mM", in ["NM"]["RECEIVER_GAIN"] should be a unitless number. Ignore this when more complicated descriptions are required.
Error: The value, "5mm HCN probe with Z axis-gradient", 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, "5mm * 8 in", 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: The value, "Gradient shim", in ["NM"]["NUMBER_OF_SCANS"] should be a unitless number. Ignore this when more complicated descriptions are required.
Error: The value, "presat", 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: Unknown or invalid section, "CHROMATOGRAPHY".
Warning: The "ri" column at position 7 in the ["NMR_METABOLITE_DATA"]["Metabolites"] table, matches a standard column name, "retention_index". 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 "ri_type" column at position 8 in the ["NMR_METABOLITE_DATA"]["Metabolites"] table, matches a standard column name, "retention_index_type". 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 standard column, "other_id", was found in the METABOLITES table as "other_id". If this column contains database IDs for standard databases such as KEGG, PubChem, HMDB, etc., it is recommended to make individual columns for these and not lump them together into a less descriptive "other_id" column.
Error: Column(s) with no name were found in the ["NMR_METABOLITE_DATA"]["Metabolites"] table.
Warning: The "inchi_key" column at position 3 in the ["NMR_METABOLITE_DATA"]["Metabolites"] table has all null values.
Warning: The "other_id" column at position 5 in the ["NMR_METABOLITE_DATA"]["Metabolites"] table has all null values.
Warning: The "other_id_type" column at position 6 in the ["NMR_METABOLITE_DATA"]["Metabolites"] table has all null values.
Warning: The "ri" column at position 7 in the ["NMR_METABOLITE_DATA"]["Metabolites"] table has all null values.
Warning: The "ri_type" column at position 8 in the ["NMR_METABOLITE_DATA"]["Metabolites"] table has all null values.
Warning: The "moverz_quant" column at position 9 in the ["NMR_METABOLITE_DATA"]["Metabolites"] table has all null values.
Warning: The "" column at position 10 in the ["NMR_METABOLITE_DATA"]["Metabolites"] table has all null values.
