A legitimate value should be provided for this required key. Error: The value, "280℃", in ["CHROMATOGRAPHY"]["COLUMN_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']. Ignore this when more complicated descriptions are required. Error: An empty value or a null value was detected in ["CHROMATOGRAPHY"]["SOLVENT_A"]. A legitimate value should be provided for this required key. Error: An empty value or a null value was detected in ["CHROMATOGRAPHY"]["SOLVENT_B"]. A legitimate value should be provided for this required key. Warning: The "quantified m/z" 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 "pubchem identifieres" column at position 4 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 identifiers" column at position 5 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 "KEGG identifiers" column at position 5 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: 21 none Warning: The "KEGG identifiers" column at position 5 in the ["MS_METABOLITE_DATA"]["Metabolites"] table, matches a standard column name, "identifier". 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 identifiers" column at position 5 in the ["MS_METABOLITE_DATA"]["Metabolites"] table, matches a standard column name, "identifier", and some of the values in the column do not match the expected type or format for that column. The non-matching values are: 0 C00079  1 C00148   2 C00022 3 C00187  4 C00082  5 C00158  6 C00025    7 C00149      8 C00049  9 C00042  10 C00122    11 C00407 12 C00123 13 C00183  14 C00037 15 C00303  16 C00041 17 C00047  18 C00073 19 C00026   20 C00186  21 none 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 "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 column, "KEGG identifiers", in the ["MS_METABOLITE_DATA"]["Metabolites"] table was matched to multiple standard names, ['kegg_id', 'identifier']. This is a good indication that the values in that column should be split into the appropriate individual columns. Warning: The "retention index" column at position 2 in the ["MS_METABOLITE_DATA"]["Metabolites"] table has all null values.
