Issue Log:
Error: An empty value or a null value was detected in ["COLLECTION"]["COLLECTION_SUMMARY"]. A legitimate value should be provided for this required key.
Error: An empty value or a null value was detected in ["TREATMENT"]["TREATMENT_SUMMARY"]. A legitimate value should be provided for this required key.
Error: An empty value or a null value was detected in ["SAMPLEPREP"]["SAMPLEPREP_SUMMARY"]. A legitimate value should be provided for this required key.
Error: The value, "250°C", in ["MS"]["ION_SOURCE_TEMPERATURE"] 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: The value, "-70eV", in ["MS"]["IONIZATION_ENERGY"] should be a number followed by a space with a unit (ex. "5 V") from the following list: ['eV']. Ignore this when more complicated descriptions are required.
Error: The value, "250°C", in ["MS"]["SOURCE_TEMPERATURE"] 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 in ["MS"]["MS_COMMENTS"]. Either a legitimate value should be provided for this key, or it should be removed altogether.
Error: The value, "1ml/min", in ["CHROMATOGRAPHY"]["FLOW_RATE"] 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, "50C ramped to 250C by 12C s-1", in ["CHROMATOGRAPHY"]["INJECTION_TEMPERATURE"] 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'] or "room temperature". Ignore this when more complicated descriptions are required.
Error: The value, "230C", in ["CHROMATOGRAPHY"]["TRANSFERLINE_TEMPERATURE"] 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: The value, "30 m length x 0.25 mm internal diameter", in ["CHROMATOGRAPHY"]["SAMPLE_LOOP_SIZE"] 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, "SOLVENT_B", in ["CHROMATOGRAPHY"] is missing.
Error: The following metabolites in the, ["MS_METABOLITE_DATA"]["Data"] table were not found in the ["MS_METABOLITE_DATA"]["Metabolites"] table:
	"1_5-anhydroglucitol"
	"2_4-diaminobutyric acid minor1"
	"propane-1_3-diol NIST"
Warning: The following metabolites in the ["MS_METABOLITE_DATA"]["Data"] table appear more than once in the table:
	"threonic acid"
	"cytidine"
Error: The following metabolites in the ["MS_METABOLITE_DATA"]["Metabolites"] table were not found in the ["MS_METABOLITE_DATA"]["Data"] table:

Warning: The "inchi_key" column at position 6 in the ["MS_METABOLITE_DATA"]["Metabolites"] table, matches a standard column name, "inchi_key", and some of the values in the column do not match the expected type or format for that column. The non-matching values are:

156    C00499
Warning: The "ri" column at position 3 in the ["MS_METABOLITE_DATA"]["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" column at position 3 in the ["MS_METABOLITE_DATA"]["Metabolites"] table, matches a standard column name, "retention_index", and some of the values in the column do not match the expected type or format for that column. The non-matching values are:
148    Peak Area
149    Peak Area
153    Peak Area
Warning: The "ri_type" column at position 4 in the ["MS_METABOLITE_DATA"]["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 "ri_type" column at position 4 in the ["MS_METABOLITE_DATA"]["Metabolites"] table, matches a standard column name, "retention_index_type", and some of the values in the column do not match the expected type or format for that column. The non-matching values are:

Warning: The column pair, "ri" and "ri_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.
