"5-6") followed by a space with a unit (ex. "5 V") from the following list: ['weeks', 'days', 'months', 'years']. Ignore this when more complicated descriptions are required. Error: An empty value or a null value was detected for the subsection, "SAMPLEPREP_PROTOCOL_ID", in the "SAMPLEPREP" section. Either a legitimate value should be provided for this subsection, or it should be removed altogether. Error: An empty value or a null value was detected for the subsection, "PROCESSING_METHOD", in the "SAMPLEPREP" section. Either a legitimate value should be provided for this subsection, or it should be removed altogether. Error: An empty value or a null value was detected for the subsection, "FLOW_GRADIENT", in the "CHROMATOGRAPHY" section. A legitimate value should be provided for this required subsection. Error: The value, "330˚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. Error: An empty value or a null value was detected for the subsection, "SOLVENT_A", in the "CHROMATOGRAPHY" section. A legitimate value should be provided for this required subsection. Error: An empty value or a null value was detected for the subsection, "SOLVENT_B", in the "CHROMATOGRAPHY" section. A legitimate value should be provided for this required subsection. Error: Unknown or invalid section, "FACTORS". Error: SUBJECT_SAMPLE_FACTORS section missing sample ID(s). The following IDs were found in the MS_METABOLITE_DATA section but not in the SUBJECT_SAMPLE_FACTORS: "" Warning: The "quant mz" 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 "mass spec" column at position 4 in the METABOLITES table, matches a standard column name, "mass_spectrum". 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" column at position 5 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" column at position 6 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 "ret.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 "ret.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. Error: Column(s) with no name were found in the MS_METABOLITE_DATA table. Error: The section, MS_METABOLITE_DATA, has a mismatch between the number of headers and the number of elements in each line. Either a line(s) has more values than headers or there are too few headers.
