Issue Log:
Error: An empty value or a null value was detected for the subsection, "COLLECTION_SUMMARY", in the "COLLECTION" section. A legitimate value should be provided for this required subsection.
Error: The value, "3500", for the subsection, "CAPILLARY_VOLTAGE", in the "MS" section should be a number followed by a space with a unit (ex. "5 V") from the following list: ['V', 'kV']. Ignore this when more complicated descriptions are required.
Error: The value, "13 l/min", for the subsection, "DRY_GAS_FLOW", in the "MS" section should be a number followed by a space with a unit (ex. "5 V") from the following list: ['L/hr', 'L/min']. Ignore this when more complicated descriptions are required.
Error: The value, "200", for the subsection, "DRY_GAS_TEMP", in the "MS" 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.
Error: The value, "175", for the subsection, "FRAGMENT_VOLTAGE", in the "MS" section should be a number followed by a space with a unit (ex. "5 V") from the following list: ['V']. Ignore this when more complicated descriptions are required.
Error: The value, "325", for the subsection, "ION_SOURCE_TEMPERATURE", in the "MS" 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.
Error: The value, "1000", for the subsection, "ION_SPRAY_VOLTAGE", in the "MS" section should be a number followed by a space with a unit (ex. "5 V") from the following list: ['V', 'kV']. Ignore this when more complicated descriptions are required.
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: The value, "11 l/min", for the subsection, "DESOLVATION_GAS_FLOW", in the "MS" section should be a number followed by a space with a unit (ex. "5 V") from the following list: ['L/hr', 'L/min']. Ignore this when more complicated descriptions are required.
Error: The value, "750", for the subsection, "OCTPOLE_VOLTAGE", in the "MS" section should be a number followed by a space with a unit (ex. "5 V") from the following list: ['V']. Ignore this when more complicated descriptions are required.
Error: The value, "65", for the subsection, "SKIMMER_VOLTAGE", in the "MS" section should be a number followed by a space with a unit (ex. "5 V") from the following list: ['V']. Ignore this when more complicated descriptions are required.
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: An empty value or a null value was detected for the subsection, "INSTRUMENT_NAME", in the "CHROMATOGRAPHY" section. A legitimate value should be provided for this required subsection.
Error: The value, "3500", for the subsection, "CAPILLARY_VOLTAGE", in the "CHROMATOGRAPHY" section should be a number followed by a space with a unit (ex. "5 V") from the following list: ['V', 'kV']. Ignore this when more complicated descriptions are required.
Error: The value, "5 seconds", for the subsection, "WEAK_WASH_VOLUME", 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" 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" 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.
Warning: The "Adduct" column at position 5 in the METABOLITES table may have incorrect values. 90% or more of the values are the same, but 10% or less are different.
