Comet parameter: num_results
         
         - This parameter controls the number of peptide search results that
         are stored internally.
         
- Depending on what post-processing tools are used, one may want to
         set this to the same value as num_output_lines.
         
- When this parameter is set to a value greater than
         num_output_lines, it allows
         the SpRank value to span a larger range which may be helpful for
         tools like PeptideProphet or Percolator (not likely though).
         
- Valid values are any integer between 1 and 100.
         
- The default value is "100" if this parameter is missing.
         
Example:
         
num_results = 50
