How Quanto reads classic ChemStation .D folders and imports ChemStation methods. For MassHunter .D (AcqData) and OpenLab CDS (.dx data / .pmx methods), see Compatibility and Troubleshooting.

Raw data layout

Item Notes
Sample .D folder
SCAN / primary MS data.ms
SIM dataSim.ms
Modes Scan , Sim , or ScanAndSim when both files are present
SIM windows Often from classic acqmeth.txt

Native reader: DataMs (Sample.Open / TryExtract, same shape as AcqData.SampleIndex) via the AgilentChemStationDataProvider add-in. No index conversion step — unlike MassHunter indexed data.

Method import

Source What you point at What comes in
ChemStation quant method .M method folder containing qdb.mth Compounds from ChemStation QDB (AgilentCsMethod)

Import uses Method → Load / Import — Replace or Append (Method design).
