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, "3500", in ["MS"]["CAPILLARY_VOLTAGE"] should be a number followed by a space with a unit (ex. "5 V") from the following list: ['V', 'kV']. Ignore this when more complicated descriptions are required.
Error: The value, "13 l/min", in ["MS"]["DRY_GAS_FLOW"] should be a number followed by a space with a unit (ex. "5 V") from the following list: ['L/hr', 'L/min']. Ignore this when more complicated descriptions are required.
Error: The value, "200", in ["MS"]["DRY_GAS_TEMP"] 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, "175", in ["MS"]["FRAGMENT_VOLTAGE"] should be a number followed by a space with a unit (ex. "5 V") from the following list: ['V']. Ignore this when more complicated descriptions are required.
Error: The value, "325", 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, "1000", in ["MS"]["ION_SPRAY_VOLTAGE"] should be a number followed by a space with a unit (ex. "5 V") from the following list: ['V', 'kV']. Ignore this when more complicated descriptions are required.
Error: The value, "Neg", in ["MS"]["IONIZATION"] should not be "positive" or "negative". "ION_MODE" is where that should be indicated.
Error: The value, "11 l/min", in ["MS"]["DESOLVATION_GAS_FLOW"] should be a number followed by a space with a unit (ex. "5 V") from the following list: ['L/hr', 'L/min']. Ignore this when more complicated descriptions are required.
Error: The value, "750", in ["MS"]["OCTPOLE_VOLTAGE"] should be a number followed by a space with a unit (ex. "5 V") from the following list: ['V']. Ignore this when more complicated descriptions are required.
Error: The value, "65", in ["MS"]["SKIMMER_VOLTAGE"] should be a number followed by a space with a unit (ex. "5 V") from the following list: ['V']. 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, "3500", in ["CHROMATOGRAPHY"]["CAPILLARY_VOLTAGE"] should be a number followed by a space with a unit (ex. "5 V") from the following list: ['V', 'kV']. Ignore this when more complicated descriptions are required.
Error: The value, "5 seconds", in ["CHROMATOGRAPHY"]["WEAK_WASH_VOLUME"] 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, "Autosampler temp 4 C", in ["CHROMATOGRAPHY"]["TARGET_SAMPLE_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 following metabolites in the, ["MS_METABOLITE_DATA"]["Data"] table were not found in the ["MS_METABOLITE_DATA"]["Metabolites"] table:
	"1-octadecanoyl-2-(9Z-octadecenoyl)-sn-glycero-3-phospho-(1^-sn-glycerol)"
Error: The following metabolites in the ["MS_METABOLITE_DATA"]["Metabolites"] table were not found in the ["MS_METABOLITE_DATA"]["Data"] table:
	"1-octadecanoyl-2-(9Z-octadecenoyl)-sn-glycero-3-phospho-(1'-sn-glycerol)"
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 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 ["MS_METABOLITE_DATA"]["Metabolites"] table has all null values.
Warning: The "kegg_id" column at position 7 in the ["MS_METABOLITE_DATA"]["Metabolites"] table has all null values.
Warning: The "other_id" column at position 8 in the ["MS_METABOLITE_DATA"]["Metabolites"] table has all null values.
Warning: The "other_id_type" column at position 9 in the ["MS_METABOLITE_DATA"]["Metabolites"] table has all null values.
Warning: The "pubchem_id" column at position 5 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.
