Experimental classes:
This TOPP-tool is not well tested and not all features might be properly implemented and tested!

This tool corrects the m/z entries of MS/MS spectra by using MS1 information. Therefore, MS1 spectra must be supplied as profile mode spectra. The isotope distribution of the peptide in the MS1 level information are then used to determine the exact position of the monoisotopic peak. If no isotope distribution can be found the original entry is kept. As a side effect of determining the exact position of the monoisotopic peak is that the charge state is also annotated.

This implementation uses the isotopewavelet featurefinder and sets the monoisotopic peak (and the charge) to the nearest feature.

The command line parameters of this tool are:
