The conversion of the ''raw'' ion count data acquired by the machine into peak lists for further processing is usually called peak picking. The choice of the algorithm should mainly depend on the resolution of the data. As the name implies, the high_res algorithm is fit for high resolution data.

Finding the right parameters for the is explained in the TOPP tutorial.

The command line parameters of this tool are:

For the parameters of the algorithm section see the algorithm documentation:
PeakPickerHiRes

In the following table you, can find example values of the most important algorithm parameters for different instrument types.
These parameters are not valid for all instruments of that type, but can be used as a starting point for finding suitable parameters.
