Error: An empty value or a null value was detected for the subsection, "MS_COMMENTS", in the "MS" section. Either a legitimate value should be provided for this subsection, or it should be removed altogether.
Error: An empty value or a null value was detected for the subsection, "INSTRUMENT_NAME", in the "CHROMATOGRAPHY" section. A legitimate value should be provided for this required subsection.
Error: The required property, "FLOW_GRADIENT", in the "CHROMATOGRAPHY" section  is missing.
Error: The required property, "FLOW_RATE", in the "CHROMATOGRAPHY" section  is missing.
Error: The required property, "COLUMN_TEMPERATURE", in the "CHROMATOGRAPHY" section  is missing.
Error: The required property, "SOLVENT_A", in the "CHROMATOGRAPHY" section  is missing.
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:
	"3a_7a_12a-trihydroxycholestanoic acid"
Error: The following metabolites in the METABOLITES table were not found in the MS_METABOLITE_DATA table:
	"3a,7a,12a-trihydroxycholestanoic acid"
Warning: The "ri" column at position 3 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 4 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 "moverz_quant" column at position 2 in the METABOLITES table has all null values.
Warning: The "ri" column at position 3 in the METABOLITES table has all null values.
Warning: The "ri_type" column at position 4 in the METABOLITES table has all null values.
Warning: The "inchi_key" column at position 6 in the METABOLITES table has all null values.
Warning: The "kegg_id" column at position 7 in the METABOLITES table has all null values.
