Issue Log:
Error: The value, "1 mL min-1", 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, "50-330", 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 following metabolites in the, ["MS_METABOLITE_DATA"]["Data"] table were not found in the ["MS_METABOLITE_DATA"]["Metabolites"] table:
	"1_5-anhydroglucitol"
	"2_5-dihydroxypyrazine"
	"2_6-diaminopimelic acid"
	"2_8-dihydroxyquinoline"
	"2^-deoxyguanosine"
	"5_6-dihydrouracil"
Error: The following metabolites in the ["MS_METABOLITE_DATA"]["Metabolites"] table were not found in the ["MS_METABOLITE_DATA"]["Data"] table:
	"1,5-anhydroglucitol"
	"2,5-dihydroxypyrazine"
	"2,6-diaminopimelic acid"
	"2,8-dihydroxyquinoline"
	"2'-deoxyguanosine"
	"5,6-dihydrouracil"
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.
Warning: The "10318_Calving_Met" column at position 209 in the ["MS_METABOLITE_DATA"]["Data"] table has all null values.
Warning: The "10251_Prepartum_Met" column at position 298 in the ["MS_METABOLITE_DATA"]["Data"] table has all null values.
Warning: The "10260_Prepartum_Met" column at position 304 in the ["MS_METABOLITE_DATA"]["Data"] table has all null values.
Error: Column(s) with no name were found in the ["MS_METABOLITE_DATA"]["Metabolites"] table.
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.
