Issue Log:
Error: The value, "Neg", for the subsection, "IONIZATION", in the "MS" section should not be "positive" or "negative". "ION_MODE" is where that should be indicated.
Error: An empty value or a null value was detected for the subsection, "MS_COMMENTS", in the "MS" section. Either a legitimate value should be provided for this subsection, or it should be removed altogether.
Error: The value, "3uL", for the subsection, "SAMPLE_INJECTION", in the "CHROMATOGRAPHY" section should be a number followed by a space with a unit (ex. "5 V") from the following list: ['μL', 'uL']. Ignore this when more complicated descriptions are required.
Error: The value, "Autosampler temp 4 C", for the subsection, "TARGET_SAMPLE_TEMPERATURE", in the "CHROMATOGRAPHY" section should be a number 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 "m/z rounded" column at position 2 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 "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 "RT rounded" column at position 4 in the METABOLITES table, matches a standard column name, "retention_time". 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.
