Actually it appears that the limit is 500 so it should work with the
original poster's data set.

Dave, have you tried just using the binary that was compiled for SunOS
4.1.x under binary compatibility mode -- I think that we use it right out
of the box without needing to tweak code. I did hit a limit with a very
large dataset (~1000), but I think it was a limit in the display window.
When I reduced the font to 8 pt, I was able to see the whole tree. But
this implies that there may be a limit (about 1500?) to display trees in
"phenogram" format -- I don't even want to think about a radial tree with
Has anyone heard of any efforts to port treetool to java? I don't have
the time myself and have not been successful in persuading others yet, but
I think that a java applet to build phylogenetic trees would be very
