## Comet parameter: show_fragment_ions

- This parameter affects .out files only i.e. output_outfiles set to 1.
- This parameter controls whether or not the theoretical fragment ion masses for the top peptide hit are calculated and dislayed at the end of an .out file.
- Valid values are 0 and 1.
- The default value is "0" if this parameter is missing.

Example:
`show_fragment_ions = 0`
`show_fragment_ions = 1`
