Issue Log:
Error: An empty value or a null value was detected in ["PROJECT"]["ADDRESS"]. A legitimate value should be provided for this required key.
Error: An empty value or a null value was detected in ["PROJECT"]["PHONE"]. A legitimate value should be provided for this required key.
Error: An empty value or a null value was detected in ["STUDY"]["ADDRESS"]. A legitimate value should be provided for this required key.
Error: An empty value or a null value was detected in ["STUDY"]["PHONE"]. A legitimate value should be provided for this required key.
Error: An empty value or a null value was detected in ["CHROMATOGRAPHY"]["INSTRUMENT_NAME"]. A legitimate value should be provided for this required key.
Error: An empty value or a null value was detected in ["CHROMATOGRAPHY"]["COLUMN_NAME"]. A legitimate value should be provided for this required key.
Error: The required property, "FLOW_GRADIENT", in ["CHROMATOGRAPHY"] is missing.
Error: The required property, "FLOW_RATE", in ["CHROMATOGRAPHY"] is missing.
Error: The required property, "COLUMN_TEMPERATURE", in ["CHROMATOGRAPHY"] is missing.
Error: The required property, "SOLVENT_A", in ["CHROMATOGRAPHY"] is missing.
Error: The required property, "SOLVENT_B", in ["CHROMATOGRAPHY"] is missing.
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 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 "13C-Glc-plate-2-cells" column at position 5 in the ["MS_METABOLITE_DATA"]["Data"] table may have incorrect values. 90% or more of the values are the same, but 10% or less are different.
Warning: The "unlabeled-plate-1-cells" column at position 6 in the ["MS_METABOLITE_DATA"]["Data"] table may have incorrect values. 90% or more of the values are the same, but 10% or less are different.
Warning: The "unlabeled-plate-2-cells" column at position 7 in the ["MS_METABOLITE_DATA"]["Data"] table may have incorrect values. 90% or more of the values are the same, but 10% or less are different.
Warning: The "ri" column at position 3 in the ["MS_METABOLITE_DATA"]["Metabolites"] table has all null values.
Warning: The "ri_type" column at position 4 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 has all null values.
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.
