Issue Log:
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: 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, "350 ul/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 required property, "FLOW_GRADIENT", in ["CHROMATOGRAPHY"] is missing.
Error: The required property, "COLUMN_TEMPERATURE", in ["CHROMATOGRAPHY"] is missing.
Warning: The "Moverz Quant" column at position 3 in the ["MS_METABOLITE_DATA"]["Metabolites"] table, matches a standard column name, "moverz_quant". 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 "mass spectrum" column at position 7 in the ["MS_METABOLITE_DATA"]["Metabolites"] table, matches a standard column name, "mass_spectrum". 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 "PubChem CID" column at position 5 in the ["MS_METABOLITE_DATA"]["Metabolites"] table, matches a standard column name, "pubchem_id". 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 "KEGG ID" column at position 6 in the ["MS_METABOLITE_DATA"]["Metabolites"] table, matches a standard column name, "kegg_id". 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 "Local ID" column at position 4 in the ["MS_METABOLITE_DATA"]["Metabolites"] table, matches a standard column name, "other_id". 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 "Retention Index" column at position 2 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 column "Local ID" was found in the ["MS_METABOLITE_DATA"]["Metabolites"] table, but this column implies that another column, "other_id_type", should also exist, and that column was not found.
Warning: The column "Retention Index" was found in the ["MS_METABOLITE_DATA"]["Metabolites"] table, but this column implies that another column, "retention_index_type", should also exist, and that column was not found.
Warning: The standard column, "other_id", was found in the METABOLITES table as "Local 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 "Moverz Quant" column at position 3 in the ["MS_METABOLITE_DATA"]["Metabolites"] table has all null values.
Warning: The "Local ID" column at position 4 in the ["MS_METABOLITE_DATA"]["Metabolites"] table has all null values.
Warning: The "KEGG ID" column at position 6 in the ["MS_METABOLITE_DATA"]["Metabolites"] table has all null values.
