Issue Log:
Error: An empty value or a null value was detected for the subsection, "ADDRESS", in the "PROJECT" section. A legitimate value should be provided for this required subsection.
Error: An empty value or a null value was detected for the subsection, "PHONE", in the "PROJECT" section. A legitimate value should be provided for this required subsection.
Error: An empty value or a null value was detected for the subsection, "ADDRESS", in the "STUDY" section. A legitimate value should be provided for this required subsection.
Error: An empty value or a null value was detected for the subsection, "PHONE", in the "STUDY" section. A legitimate value should be provided for this required subsection.
Error: The value, "600 MHZ", for the subsection, "SPECTROMETER_FREQUENCY", in the "NM" section 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", 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, "0.05 mM", for the subsection, "RECEIVER_GAIN", in the "NM" section should be a unitless number. Ignore this when more complicated descriptions are required.
Error: The value, "5mm HCN probe with Z axis-gradient", for the subsection, "PRESATURATION_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, "5mm * 8 in", for the subsection, "TEMPERATURE", in the "NM" section 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", for the subsection, "NUMBER_OF_SCANS", in the "NM" section should be a unitless number. Ignore this when more complicated descriptions are required.
Error: The value, "presat", 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: Unknown or invalid section, "CHROMATOGRAPHY".
Warning: The "ri" column at position 7 in the 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 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.
Warning: The "inchi_key" column at position 3 in the METABOLITES table has all null values.
Warning: The "other_id" column at position 5 in the METABOLITES table has all null values.
Warning: The "other_id_type" column at position 6 in the METABOLITES table has all null values.
Warning: The "ri" column at position 7 in the METABOLITES table has all null values.
Warning: The "ri_type" column at position 8 in the METABOLITES table has all null values.
Warning: The "moverz_quant" column at position 9 in the METABOLITES table has all null values.
