Issue Log:
Error: The value, "50 +/-11", for the subsection, "AGE_OR_AGE_RANGE", in the "SUBJECT" section should be a number or range (ex. "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: The value, "45", 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 required property, "SOLVENT_B", in the "CHROMATOGRAPHY" section  is missing.
Error: The following metabolites in the, MS_METABOLITE_DATA table were not found in the METABOLITES table:
	"1-(Hydroxymethyl)-5_5-dimethyl-2_4-imidazolidinedione_exogenous_[M+H]+"
	"NG_ NG-dimethyl-L-arginine_[M+H]+"
Error: The following metabolites in the METABOLITES table were not found in the MS_METABOLITE_DATA table:
	"1-(Hydroxymethyl)-5,5-dimethyl-2,4-imidazolidinedione_exogenous_[M+H]+"
	"NG, NG-dimethyl-L-arginine_[M+H]+"
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 "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 "kegg_id" column at position 4 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.
