Issue Log:
Error: An empty value or a null value was detected for the subsection, "PROJECT_SUMMARY", in the "PROJECT" section. A legitimate value should be provided for this required subsection.
Error: An empty value or a null value was detected for the subsection, "ADDRESS", in the "PROJECT" section. A legitimate value should be provided for this required subsection.
Error: An empty value or a null value was detected for the subsection, "PHONE", in the "PROJECT" section. A legitimate value should be provided for this required subsection.
Error: An empty value or a null value was detected for the subsection, "ADDRESS", in the "STUDY" section. A legitimate value should be provided for this required subsection.
Error: An empty value or a null value was detected for the subsection, "PHONE", in the "STUDY" section. A legitimate value should be provided for this required subsection.
Error: The value, "Male and Female", for the subsection, "GENDER", in the "SUBJECT" section should be one of "Male", "Female", "Male, Female", "Hermaphrodite", or "N/A". Ignore this when more complicated descriptions are required.
Error: The value, "0.450.5 mL/min", for the subsection, "FLOW_RATE", 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: ['mL/min', 'uL/min', 'μL/min']. Ignore this when more complicated descriptions are required.
Error: The value, "1 L, splitless", for the subsection, "SAMPLE_INJECTION", in the "CHROMATOGRAPHY" section should be a number followed by a space with a unit (ex. "5 V") from the following list: ['μL', 'uL']. Ignore this when more complicated descriptions are required.
Error: The value, "10 L", for the subsection, "SAMPLE_SYRINGE_SIZE", in the "CHROMATOGRAPHY" section should be a number followed by a space with a unit (ex. "5 V") from the following list: ['μL', 'uL']. Ignore this when more complicated descriptions are required.
Error: The required property, "FLOW_GRADIENT", 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:
	"1_3-dihydroxyacetone"
	"2_3-dihydroxybutanoic acid"
	"2_3-dihydroxybutyric acid 1"
	"2_3-dihydroxybutyric acid 2"
	"2_3-dihydroxybutyric acid  2"
	"2_4-dihydroxybutyric acid"
	"2-butyne-1_4-diol"
	"2-methyl-3-hydroxypropanoic acid_1"
	"3_4-dihydroxybutanoic acid"
	"3_4-dihydroxybutyric acid"
	"3_4-dihydroxybutyric acid_1"
Error: The following metabolites in the METABOLITES table were not found in the MS_METABOLITE_DATA table:
	"1,3-dihydroxyacetone"
	"2,3-dihydroxybutanoic acid"
	"2,3-dihydroxybutyric acid 1"
	"2,3-dihydroxybutyric acid 2"
	"2,3-dihydroxybutyric acid  2"
	"2,4-dihydroxybutyric acid"
	"2-butyne-1,4-diol"
	"3,4-dihydroxybutanoic acid"
	"3,4-dihydroxybutyric 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 column pair, "other_id" and "other_id_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 "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.
