creating beautiful cladogram trees thanks to gnuclad

The commandline tool gnuclad allows creating beautiful cladogram trees and more. Application source code can be downloaded at and needs to be compiled before the tool is usable. When using Ubuntu (14.04) download and compilation can be done by running commands shown below in terminal:

tar -xvf gnuclad-0.2.4.tar.gz
cd gnuclad-0.2.4/
sh configure
sudo make install

Following this, the tool is usable from commandline. To render a cladogram tree data needs to be formatted as CSV file while detailed configuration options are placed in a separate configuration file. You can see an example below:

gnuclad example.csv SVG example.conf
