## Comet parameter: remove_precursor_peak

- This parameter controls excluding/removing any precursor signals from the input MS/MS spectrum.
- An input value of 0 will not perform any precursor removal.
- An input value of 1 will remove all peaks around the precursor m/z.
- An input value of 2 will remove all charge reduced precursor peaks as expected to be present for ETD/ECD spectra.
- This parameter works in conjuction with remove_precursor_tolerance to specify the tolerance around each precuror m/z that will be removed.
- Valid values are 0, 1, and 2.
- The default value is "0" if this parameter is missing.

Example:
`remove_precursor_peak = 0`
`remove_precursor_peak = 1`
`remove_precursor_peak = 2`
