Comment transformer un Count en Distribution?

Un Count se convertit simplement en Distribution en utilisant la méthode statique countToDistribution() de la classe DistributionTools.

import org.biojava.bio.dist.*;
import org.biojava.bio.seq.*;
import org.biojava.bio.symbol.*;
 
public class Count2Dist {
  public static void main(String[] args) {
    FiniteAlphabet alpha = RNATools.getRNA();
    AlphabetIndex index = AlphabetManager.getAlphabetIndex(alpha);
    try {
      //faire un Count
      Count c = new IndexedCount(alpha);
      c.increaseCount(RNATools.a(),35.0);
      c.increaseCount(RNATools.c(),44.0);
      c.increaseCount(RNATools.g(),68.0);
      c.increaseCount(RNATools.u(),34.0);
 
      System.out.println("COUNT");
 
      for (int i = 0; i < alpha.size(); i++) {
        AtomicSymbol s = (AtomicSymbol)index.symbolForIndex(i);
        System.out.println(s.getName()+" : "+c.getCount(s));
      }
 
      //transformer en Distribution
      Distribution d = DistributionTools.countToDistribution(c);
 
      System.out.println("\nDISTRIBUTION");
 
      for (int i = 0; i < alpha.size(); i++) {
        Symbol s = index.symbolForIndex(i);
        System.out.println(s.getName()+" : "+d.getWeight(s));
      }
    }
    catch (Exception ex) {
      ex.printStackTrace();
    }
  }
}
