Issue Log:
Error: An empty value or a null value was detected for the subsection, "TREATMENT_SUMMARY", in the "TREATMENT" section. A legitimate value should be provided for this required subsection.
Error: The value, "0.5mM", for the subsection, "STANDARD_CONCENTRATION", in the "NM" section should be a number followed by a space with a unit (ex. "5 V") from the following list: ['mM']. Ignore this when more complicated descriptions are required.
Error: The value, "300K", for the subsection, "TEMPERATURE", in the "NM" section should be a number followed by a space with a unit (ex. "5 V") from the following list: ['°C', 'C', 'K']. Ignore this when more complicated descriptions are required.
Error: The value, "3.9s", for the subsection, "ACQUISITION_TIME", in the "NM" section should be a number followed by a space with a unit (ex. "5 V") from the following list: ['s']. Ignore this when more complicated descriptions are required.
Error: The value, "2s", for the subsection, "RELAXATION_DELAY", in the "NM" section should be a number followed by a space with a unit (ex. "5 V") from the following list: ['s', 'ms', 'us', 'μs']. Ignore this when more complicated descriptions are required.
Error: The value, "12.02ppm", for the subsection, "SPECTRAL_WIDTH", in the "NM" section should be a number followed by a space with a unit (ex. "5 V") from the following list: ['ppm', 'Hz']. Ignore this when more complicated descriptions are required.
Error: Unknown or invalid section, "CHROMATOGRAPHY".
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 "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.
Warning: The "KEGG ID" column at position 5 in the METABOLITES table has all null values.
