Comet parameter: minimum_intensity
         
         - A floating point number indicating the minimum intensity value
         for input the input peaks.
         
- If an experimental MS/MS peak intensity is less than this value,
         it will not be read in and used in the analysis.
         
- This is one mechanism to get rid of systemmatic background noise
         that has a near contant peak intensity.
         
- If a peak does not pass this minimum intensity threshold, it will
         also not be counted towards the minimum_peaks
         parameter.
         
- Valid values are any floating point number.
         
- The default value is "0.0" if this parameter is missing.
         
Example:
         
minimum_intensity = 100.0
