"5-6") followed by a space with a unit (ex. "5 V") from the following list: ['mL/min', 'uL/min', 'μL/min']. Ignore this when more complicated descriptions are required. Error: The value, "50", for the subsection, "COLUMN_TEMPERATURE", 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: ['°C', 'C']. Ignore this when more complicated descriptions are required. Error: The value, "18min", 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 required property, "FLOW_GRADIENT", in the "CHROMATOGRAPHY" section is missing. Error: The following metabolites in the, MS_METABOLITE_DATA table were not found in the METABOLITES table: "3_4 DIHYDROXYMANDELATE" "3_4-DIHYDROXYPHENYLGLYCOL" "N_N-DIMETHYLARGININE" "SUGAR ALCOHOL (RIBITOL_ XYLITOL_ ARABITOL)" Error: The following metabolites in the METABOLITES table were not found in the MS_METABOLITE_DATA table: "3,4 DIHYDROXYMANDELATE" "3,4-DIHYDROXYPHENYLGLYCOL" "N,N-DIMETHYLARGININE" "SUGAR ALCOHOL (RIBITOL, XYLITOL, ARABITOL)" Warning: The "kegg_id" column at position 4 in the METABOLITES table, matches a standard column name, "kegg_id", and some of the values in the column do not match the expected type or format for that column. The non-matching values are: 32 D4-TAURINE 44 FRUCTOSE BISPHOSPHATE 46 G6P and G1P 61 HEXOES (GLUCOSE) 85 METHYLGLUTARATE 87 MONOMETHYLGLUTARATE 88 N-ACETYLALANINE 89 N-ACETYLASPARAGINE 93 N-ACETYLGLYCINE 98 N-ACETYLSERINE 99 N-ACETYLTRYPTOPHAN 107 OPHTHALMATE 110 PENTOSE 124 SUGAR ALCOHOL (RIBITOL, XYLITOL, ARABITOL) 126 THREONINE and HOMOSERINE 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 column pair, "ri" and "ri_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 "pubchem_id" column at position 2 in the METABOLITES table has all null values. 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_type" column at position 8 in the METABOLITES table has all null values.
