Comet parameter: digest_mass_range
- Defines the mass range of peptides to search (based on MH+ or the singly
protonated mass).
- This parameter has two decimal values.
- The first value is the lower mass cutoff and the second value is
the high mass cutoff.
- Only spectra with experimental MH+ masses in within the defined
mass ranges are searched.
- Valid values are two decimal numbers where the first number must
be less or equal to the second number.
- The default value is "0.0 10000.0" if this parameter is missing.
Example:
digest_mass_range = 600.0 5000.0 search only 600.0 to 5000.0 mass range
digest_mass_range = 0.0 6500.0 search all spectra with peptide masses between 0.0 and 6000.0
