Issue Log:
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, "40°C", 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.
Warning: The "Molecular Weight" column at position 6 in the ["MS_METABOLITE_DATA"]["Metabolites"] table, matches a standard column name, "mass". 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 "Compounds" column at position 2 in the ["MS_METABOLITE_DATA"]["Metabolites"] table, matches a standard column name, "compound". 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 "Ion mode" column at position 7 in the ["MS_METABOLITE_DATA"]["Metabolites"] table, matches a standard column name, "ion". 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 "Ion mode" column at position 7 in the ["MS_METABOLITE_DATA"]["Metabolites"] table, matches a standard column name, "ion", 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    Negative
1    Negative
2    Negative
3    Negative
4    Negative
5    Negative
6    Negative
7    Negative
Warning: The "kegg_map" column at position 13 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 "HMDB" column at position 11 in the ["MS_METABOLITE_DATA"]["Metabolites"] table, matches a standard column name, "hmdb_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 "CAS" column at position 12 in the ["MS_METABOLITE_DATA"]["Metabolites"] table, matches a standard column name, "cas_number". 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 "Ionization model" column at position 8 in the ["MS_METABOLITE_DATA"]["Metabolites"] table, matches a standard column name, "ionization_mode". 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 "Ionization model" column at position 8 in the ["MS_METABOLITE_DATA"]["Metabolites"] table, matches a standard column name, "ionization_mode", 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    [M-H]-
1    [M-H]-
2    [M-H]-
3    [M-H]-
4    [M-H]-
5    [M-H]-
6    [M-H]-
7    [M-H]-
