|  Program for search all tie neighbor-joining trees and UPGMA trees and |

These programs run on Sun workstations and other UNIX systems.
This directory have five programs:
    njbtie  -- search all neighbor-joining (NJ) trees and UPGMA trees
    postree -- create a postscript file of trees
  and example files:
    testseq -- example sequences
    testseq.NJTIE1     -- an NJ treefile of testseq
    testseq.NJTIE2     -- an NJ treefile of testseq
    testseq.UPTIE2     -- an NJ treefile of testseq
    testseq.NJTIE1.ps  -- postscript file of testseq.NJTIE1

The problems of tie trees for NJ method and UPGMA are discused in

N. Takezaki 1998. Tie trees generated by distance methods of phylogenetic 
reconstruction. Molecular Biology and Evolution 15:727-777.
