clgui - perform 3D interactive Quartet Tree Reconstruction on a
distance matrix to produce a binary tree
clgui [ distmatrix.clb ] [ treefile.dot ]
clgui tries to find an optimal tree to represent a distance matrix
calculated in realtime. It uses the Quartet Tree Reconstruction
method. The program starts with a random tree, and continues to try
small modifications to improve the tree score. Eventually, the tree
will stop easily improving. Move the camera with the mouse and
keyboard, or experiment with the w (wireframe) and other commands.
Explore the 3D virtual space to understand the statistical
relationships among your data.
Double clicking with both mouse buttons will reset the camera view.
clgui can calculate distance matrix files in realtime. If a large
amount of data must be processed, it is better to precalculate the
distance matrix. Input files for this program can be created by ncd
(1). This provides a smoother and more convenient way to create a
binary distance matrix file via the -b command line option.
When starting clgui, you can begin with a clean slate and no options.
Or one may just specify a distance matrix filename on the command line
when starting clgui. If you do not specify a name, it will look for a
file called distmatrix.clb in the current directory and load it
immediately if found. If you specify both a distance matrix and a tree
file, then clgui will provide an interactive 3D display to explore the
tree by moving, panning, and zooming the camera.
To create trees with more control, use the maketree command from the
libqsearch package. For more information on the details of this
algorithm, please see Clustering by Compression by Cilibrasi and
Vitanyi in IEEE Trans. Information Theory, 51:4(2005) or at url

per-user configuration file, overrides systemwide default; see
complearn(5) for further details.
If any of the files cannot be read, an error will be printed and the
program exits with a nonzero exit code.
