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, "0.5l", in ["CHROMATOGRAPHY"]["SAMPLE_INJECTION"] 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, "7.7 PSI (initial condition)", in ["CHROMATOGRAPHY"]["COLUMN_PRESSURE"] 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 value, "50C ramped to 250C by 12C/s", 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, "FLOW_GRADIENT", in ["CHROMATOGRAPHY"] is missing.

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_3-dihydroxybutanoic acid NIST"

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:
143    C00077
144    C00208
145    C00639
146    C02095
147    C00712

Warning: The "kegg_id" column at position 7 in the ["MS_METABOLITE_DATA"]["Metabolites"] table, matches a standard column name, "kegg_id", and some of the values in the column do not match the expected type or format for that column. The non-matching values are:
1      0

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_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:
143       6262
144     439186

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 "ri_type" column at position 4 in the ["MS_METABOLITE_DATA"]["Metabolites"] table may have incorrect values. 90% or more of the values are the same, but 10% or less are different.
Warning: The "other_id_type" column at position 9 in the ["MS_METABOLITE_DATA"]["Metabolites"] table may have incorrect values. 90% or more of the values are the same, but 10% or less are different.
