Either a legitimate value should be provided for this subsection, or it should be removed altogether. Error: The required property, "FLOW_GRADIENT", in the "CHROMATOGRAPHY" section is missing. Error: The required property, "FLOW_RATE", in the "CHROMATOGRAPHY" section is missing. Error: The required property, "COLUMN_TEMPERATURE", in the "CHROMATOGRAPHY" section is missing. Error: The required property, "SOLVENT_A", in the "CHROMATOGRAPHY" section is missing. Error: The required property, "SOLVENT_B", in the "CHROMATOGRAPHY" section is missing. Warning: The "quantified m/z" column at position 3 in the 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 ID" column at position 4 in the 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 5 in the 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 "retention index" column at position 2 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 column "retention index" was found in the METABOLITES table, but this column implies that another column, "retention_index_type", should also exist, and that column was not found. Warning: The "1A-180" column at position 2 in the MS_METABOLITE_DATA table has all null values. Warning: The "1A-480" column at position 3 in the MS_METABOLITE_DATA table has all null values. Warning: The "2A-180" column at position 6 in the MS_METABOLITE_DATA table has all null values. Warning: The "3A-180" column at position 10 in the MS_METABOLITE_DATA table has all null values. Warning: The "3A-480" column at position 11 in the MS_METABOLITE_DATA table has all null values. Warning: The "5A-180" column at position 14 in the MS_METABOLITE_DATA table has all null values. Warning: The "5A-480" column at position 15 in the MS_METABOLITE_DATA table has all null values. Warning: The "8A-180" column at position 22 in the MS_METABOLITE_DATA table has all null values. Warning: The "14A-180" column at position 26 in the MS_METABOLITE_DATA table has all null values. Warning: The "14A-480" column at position 27 in the MS_METABOLITE_DATA table has all null values. Warning: The "14B-180" column at position 28 in the MS_METABOLITE_DATA table has all null values. Warning: The "14B-480" column at position 29 in the MS_METABOLITE_DATA table has all null values. Warning: The "16B-180" column at position 34 in the MS_METABOLITE_DATA table has all null values. Warning: The "16B-480" column at position 35 in the MS_METABOLITE_DATA table has all null values. Warning: The "16C-480" column at position 37 in the MS_METABOLITE_DATA table has all null values. Warning: The "18A-180" column at position 38 in the MS_METABOLITE_DATA table has all null values. Warning: The "19A-180" column at position 42 in the MS_METABOLITE_DATA table has all null values. Warning: The "retention index" column at position 2 in the METABOLITES table has all null values. Warning: The "quantified m/z" column at position 3 in the METABOLITES table has all null values. Warning: The "PubChem ID" column at position 4 in the METABOLITES table has all null values.
