Issue Log:
Error: An empty value or a null value was detected in ["CHROMATOGRAPHY"]["FLOW_GRADIENT"]. A legitimate value should be provided for this required key.
Error: The value 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.
Error: SUBJECT_SAMPLE_FACTORS section missing sample ID(s). The following IDs were found in the ["MS_METABOLITE_DATA"]["Data"] section but not in the SUBJECT_SAMPLE_FACTORS:
	""
Warning: The "Quantitated m/z" column at position 5 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 CID" column at position 3 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 "PubChem CID" column at position 3 in the ["MS_METABOLITE_DATA"]["Metabolites"] table, matches a standard column name, "pubchem_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:
23    C00189
24    C00140
25    C00258
26    C00116
27    C00160
Warning: The "KEGG ID" column at position 2 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 ID" column at position 2 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:
1     7036277
22       8222
23        700
24        174
25        752
26        753
27        757
Warning: The "Retention index" column at position 4 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.
Error: Column(s) with no name were found in the ["MS_METABOLITE_DATA"]["Data"] table.
Warning: The "" column at position 26 in the ["MS_METABOLITE_DATA"]["Data"] table has all null values.
