Issue Log:
Error: The required property, "STUDY_TITLE", in the "STUDY" section  is missing.
Error: The value, "40°C-50°C", 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 following metabolites in the, MS_METABOLITE_DATA table were not found in the METABOLITES table:
	"1_2-dioleoyl-GPG (18:1/18:1)"
	"1_2-dioleoyl-GPI (18:1/18:1)"
	"1_2-distearoyl-GPG (18:0/18:0)"
	"2_3-dihydroxy-2-methylbutyrate"
	"2_4-dihydroxybutyrate"
	"2^-deoxyuridine 5^-monophosphate"
	"2R_3R-dihydroxybutyrate"
	"2S_3R-dihydroxybutyrate"
	"cytidine 2^ or 3^-monophosphate (2^ or 3^-CMP)"
	"cytidine-5^-diphosphoethanolamine"
	"cytidine 5^-monophospho-N-acetylneuraminic acid"
	"uridine 5^-monophosphate (UMP)"
Error: The following metabolites in the METABOLITES table were not found in the MS_METABOLITE_DATA table:
	"1,2-dioleoyl-GPG (18:1/18:1)"
	"1,2-dioleoyl-GPI (18:1/18:1)"

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 "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" 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.
Warning: The "moverz_quant" column at position 9 in the METABOLITES table has all null values.
