Issue Log:
Error: The value, "1ml/min", in ["CHROMATOGRAPHY"]["FLOW_RATE"] should be a number or range (ex. "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", in ["CHROMATOGRAPHY"]["COLUMN_TEMPERATURE"] 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", in ["CHROMATOGRAPHY"]["ANALYTICAL_TIME"] 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 ["CHROMATOGRAPHY"] is missing.
Error: The following metabolites in the, ["MS_METABOLITE_DATA"]["Data"] table were not found in the ["MS_METABOLITE_DATA"]["Metabolites"] table:
	"3_4 DIHYDROXYMANDELATE"
	"3_4-DIHYDROXYPHENYLGLYCOL"
	"N_N-DIMETHYLARGININE"
	"SUGAR ALCOHOL (RIBITOL_ XYLITOL_ ARABITOL)"
Error: The following metabolites in the ["MS_METABOLITE_DATA"]["Metabolites"] table were not found in the ["MS_METABOLITE_DATA"]["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 ["MS_METABOLITE_DATA"]["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)

110                                       PENTOSE
124    SUGAR ALCOHOL (RIBITOL, XYLITOL, ARABITOL)
126                      THREONINE and HOMOSERINE
Warning: The "ri" column at position 7 in the ["MS_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 ["MS_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 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.
Error: Column(s) with no name were found in the ["MS_METABOLITE_DATA"]["Metabolites"] table.
Warning: The "pubchem_id" column at position 2 in the ["MS_METABOLITE_DATA"]["Metabolites"] table has all null values.
Warning: The "inchi_key" column at position 3 in the ["MS_METABOLITE_DATA"]["Metabolites"] table has all null values.
Warning: The "other_id" column at position 5 in the ["MS_METABOLITE_DATA"]["Metabolites"] table has all null values.
Warning: The "other_id_type" column at position 6 in the ["MS_METABOLITE_DATA"]["Metabolites"] table has all null values.
Warning: The "ri_type" column at position 8 in the ["MS_METABOLITE_DATA"]["Metabolites"] table has all null values.
Warning: The "" column at position 10 in the ["MS_METABOLITE_DATA"]["Metabolites"] table has all null values.
