Issue Log:
Error: The value, "55°C", for the subsection, "COLUMN_TEMPERATURE", in the "CHROMATOGRAPHY" section 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 "ri" column at position 7 in the 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 8 in the 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, "ri" and "ri_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 "BT_B1_SN" column at position 2 in the MS_METABOLITE_DATA table has all null values.
Warning: The "BT_B2_SN" column at position 3 in the MS_METABOLITE_DATA table has all null values.
Warning: The "BT_B3_SN" column at position 4 in the MS_METABOLITE_DATA table has all null values.
Warning: The "BT_B4_SN" column at position 5 in the MS_METABOLITE_DATA table has all null values.
Warning: The "BT_B5_SN" column at position 6 in the MS_METABOLITE_DATA table has all null values.
Warning: The "CA_B1_SN" column at position 12 in the MS_METABOLITE_DATA table has all null values.
Warning: The "CA_B2_SN" column at position 13 in the MS_METABOLITE_DATA table has all null values.
Warning: The "CA_B3_SN" column at position 14 in the MS_METABOLITE_DATA table has all null values.
Warning: The "CA_B4_SN" column at position 15 in the MS_METABOLITE_DATA table has all null values.
Warning: The "CA_B5_SN" column at position 16 in the MS_METABOLITE_DATA table has all null values.
Warning: The "Co_B1_SN" column at position 22 in the MS_METABOLITE_DATA table has all null values.
Warning: The "Co_B2_SN" column at position 23 in the MS_METABOLITE_DATA table has all null values.
Warning: The "Co_B3_SN" column at position 24 in the MS_METABOLITE_DATA table has all null values.
Warning: The "Co_B4_SN" column at position 25 in the MS_METABOLITE_DATA table has all null values.
Warning: The "Co_B5_SN" column at position 26 in the MS_METABOLITE_DATA table has all null values.
Warning: The "Blank_SN" column at position 33 in the MS_METABOLITE_DATA table has all null values.
Warning: The "inchi_key" column at position 3 in the METABOLITES table has all null values.
Warning: The "kegg_id" column at position 4 in the METABOLITES table has all null values.
Warning: The "other_id" column at position 5 in the METABOLITES table has all null values.
Warning: The "other_id_type" column at position 6 in the METABOLITES table has all null values.
Warning: The "ri_type" column at position 8 in the METABOLITES table has all null values.
