name
   localbest: find features with the highest Ri in a given sequence range

synopsis
   localbest(features: in, localbestp: in, bestfeatures: out,
             lowerfeatures: out, output: out)

files
   features:  A list of locations of binding sites and other features.

   bestfeatures:  A list of the features from the original file which have the
      highest Ri in a given range

   localbestp:  parameters to control the program.  The file must contain the
      following parameters, one per line:

      parameterversion: The version number of the program.  This allows the
         user to be warned if an old parameter file is used.

      window:  Features are discarded if the coordinate of another
         feature with a higher Ri is less than or equal to the window
         distance away from the one being looked at.  Note that if
         window is 100, the region accepted will be 2*100+1 = 201
         bases.

      asterisks: If character is 'A' then the filtered out features are shown
         as asterisks in a lowerfeatures file.

   lowerfeatures:  A list of the features from the original file which have the
      lower Ri values in a given range. These are the features which have been
      'discarded' by the program.

   output: messages to the user

description

   Scan often produces a features file with many sites picked up over
   a small  range. This makes the map very difficult to look at, so
   this program  attempts to filter the features and find the one with
   the highest Ri over a  small range and only keep that one.

   The user should be aware that this program discards valuable
   information in  the form of possible binding sites.  For this
   reason, it is a good idea to  not set the window at more than 1
   helix turn (10.6 bp). Sites at this  distance apart are probably
   significant and should be kept in the features  file.
