 For example, if you want to use centWave with a peakwidth from 5 to 10 and 25 ppm, findPeaksArgs would look like this:

 If you want to utilize XCMS for Step 1 of the workflow, you have to set the readMethod-parameter to "xcms" and - if you don't want to use standard values for findPeaks - pass on findPeaksArgs to the workflow.
