## Comet parameter: clear_mz_range

- This parameter is intended for iTRAQ/TMT type data where one might want to remove the reporter ion signals in the MS/MS spectra prior to searching.
- Defines the m/z range to clear out in each MS/MS spectra
- This parameter has two decimal values.
- The first value is the lower mass cutoff and the second value is the high mass cutoff.
- Valid values are two decimal numbers where the first number must be less or equal to the second number.
- All peaks between the two decimal values are cleared out.
- The default value is "0.0 0.0" if this parameter is missing.

Example:
`clear_mz_range = 0.0 0.0` parameter is ignored
`clear_mz_range = 112.5 121.5` ignore all peaks between 112.5 and 121.5 m/z for iTRAQ 8-plex
`clear_mz_range = 125.5 131.5` ignore all peaks between 125.5 and 131.5 m/z for TMT
