Hi, I have data in the form of a distance matrix (well, similarity, but easily convertible). I would like a hierarchical clustering software which: 1) Has a good number of amalgamation rules. I want to throw as many things as I can at my data set. A good number of distance rules (Eucledian, squared, Chebychev etc.) would be nice too. 2) A nice tree display. Failing that, an output in one of the standard formats which I can display using TreeView, or somesuch. I know I can use Neighbor from Phylip, I just wondered what else is out there. Any reply would be helpful. Thanks, Iddo -- Iddo Friedberg, Ph.D. The Burnham Institute 10901 N. Torrey Pines Rd.
