    I had. I founded this class in the doc:
    Bio::Tree::DistanceFactory
    Here: http://bioperl.org/HOWTOs/html/Trees.html
    But wasn't able to find it in the bioperl distribution:
    http://search.cpan.org/~birney/bioperl-1.4/
    Anyone can help ? I'd looooove to use this DistanceFactory Class !!
    Thx !
