COSC 348: Lab09

Overview: Phylogeny inference lab 3/3

This is practice building parts that you will need for the assignment.

IMPORTANT: Submit the code you've developed for this lab (worth 1% of your final mark).

Tree visualisation

To convert the Newick format into a tree, you can use tree2dot.c. This program requires 'dot' from GraphViz. Or you can make your own implementation.

Some stuff for drawing phylogenies:

• tree2tex.c, a program for converting binary trees to LaTeX. This requires the LaTeX package qtree.sty, described in qtreenotes.tex. This prints trees in landscape mode with fairly small characters to pack up to 30 nodes on a page. Beware: you cannot use pdflatex with this.
• tree2dot.c, a program for converting binary trees to the input language of the GraphViz utility "dot". This currently uses dot's default settings.
  • Sample tree in Newick form
  • Converted to "dot" input
  • As a Postscript file
  • As a PDF file from "dot"
  • As a LaTeX file
  • As a PDF file from latex+dvips+ps2pdf
