"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: An empty value or a null value was detected for the subsection, "COLLECTION_SUMMARY", in the "COLLECTION" section. A legitimate value should be provided for this required subsection. Error: The value, "300", for the subsection, "CAPILLARY_TEMPERATURE", in the "MS" section should be a number or range (ex. "5-6") followed by a space with a unit (ex. "5 V") from the following list: ['°C', 'C']. Ignore this when more complicated descriptions are required. Error: The value, "30", for the subsection, "DRY_GAS_FLOW", in the "MS" section should be a number followed by a space with a unit (ex. "5 V") from the following list: ['L/hr', 'L/min']. Ignore this when more complicated descriptions are required. Error: The value, "350", for the subsection, "ION_SOURCE_TEMPERATURE", in the "MS" section should be a number followed by a space with a unit (ex. "5 V") from the following list: ['°C', 'C']. Ignore this when more complicated descriptions are required. Error: The value, "3500", for the subsection, "ION_SPRAY_VOLTAGE", in the "MS" section should be a number followed by a space with a unit (ex. "5 V") from the following list: ['V', 'kV']. Ignore this when more complicated descriptions are required. Error: The value, "350", for the subsection, "DESOLVATION_TEMPERATURE", in the "MS" section should be a number followed by a space with a unit (ex. "5 V") from the following list: ['°C', 'C']. Ignore this when more complicated descriptions are required. Error: The value, "18 mins", for the subsection, "ANALYTICAL_TIME", in the "CHROMATOGRAPHY" section should be a number or range (ex. "5-6") followed by a space with a unit (ex. "5 V") from the following list: ['min']. Ignore this when more complicated descriptions are required. Error: The value, "350 C", for the subsection, "CAPILLARY_VOLTAGE", in the "CHROMATOGRAPHY" section should be a number followed by a space with a unit (ex. "5 V") from the following list: ['V', 'kV']. Ignore this when more complicated descriptions are required. Error: The required property, "INSTRUMENT_NAME", in the "CHROMATOGRAPHY" section is missing. Warning: The "ri" column at position 3 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 4 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 column pair, "other_id" and "other_id_type", in the METABOLITES table should have data in the same rows, but at least one row has data in one column and nothing in the other. 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 "moverz_quant" column at position 2 in the METABOLITES table has all null values. Warning: The "ri" column at position 3 in the METABOLITES table has all null values. Warning: The "ri_type" column at position 4 in the METABOLITES table has all null values. Warning: The "inchi_key" column at position 6 in the METABOLITES table has all null values. Warning: The "other_id" column at position 8 in the METABOLITES table has all null values. Warning: The "kegg_id" column at position 7 in the METABOLITES table may have incorrect values. 90% or more of the values are the same, but 10% or less are different. Error: The section, MS, has a sub-section, INSTRUMENT_NAME, that is duplicated.
