       clgui  -  perform  3D  interactive  Quartet  Tree  Reconstruction  on a
       distance matrix to produce a binary tree


       clgui [ distmatrix.clb ] [ ]


       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


       There are no options for clgui yet.


              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.
