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, "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, "PHONE", 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, "TREATMENT_SUMMARY", in the "TREATMENT" section. A legitimate value should be provided for this required subsection.
Error: The value, "POSITIVE/NEGATIVE", for the subsection, "ION_MODE", in the "MS" section should be one of "Positive", "Negative", "Positive, Negative", or "Unspecified". Ignore this when more complicated descriptions are required.
Error: The value, "N2", for the subsection, "COLLISION_GAS", in the "MS" section should be one of "Nitrogen" or "Argon". Ignore this when more complicated descriptions are required.
Error: The value, "350°C", for the subsection, "DRY_GAS_TEMP", in the "MS" section should be a number 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: 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: The value, "40C", 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 value, "10 ?L", 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, "18 MPa", for the subsection, "COLUMN_PRESSURE", 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: ['psi', 'bar']. 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:
	"2_6-Diaminoheptanedioate"
	"5_6-Dihydrouracil"
	"5^-Methylthioadenosine"
	"7_8-Diaminononanoate"
	"Fructose 1_6-bisphosphate"
	"Pantetheine 4^-phosphate"
	"Sedoheptulose 1_7-bisphosphate"
Error: The following metabolites in the METABOLITES table were not found in the MS_METABOLITE_DATA table:
	"2,6-Diaminoheptanedioate"
	"5,6-Dihydrouracil"
	"5'-Methylthioadenosine"
	"7,8-Diaminononanoate"
	"Fructose 1,6-bisphosphate"
	"Pantetheine 4'-phosphate"
	"Sedoheptulose 1,7-bisphosphate"
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 "inchi_key" column at position 6 in the METABOLITES table has all null values.
