Hauusian program for multi-components structure system generation.

The number of atoms in hau2 version is up to 480.
Hauusian have read the files with the extensions (p1, p2):

1. Only geometry:
  log out (from Gaussian, the last geometry)
  pdb ent
  mol2 and mol (Mercury, Chemsketch)
  gjf (from Gaussian, only in the xyz format)
  geo (Geom program)
  orn (manually chosen geometry from Gaussian log file)
  xyz
Caution: the coordinate system is moved to (0,0,0) with exception of .orn files

2. geometry and frequencies:
  log out (the geometry chosen from Gaussian)
  fmt fmu fmv (Vead4)
  hau (Hauusian)
Caution: here the coordinate system is not moved 

If the geometry and frequencies are formally correct – the file .hau is automatically generated – see exemplary files
______________________

Hauusian program create the default connection matrix (with exception of .pdb files)
the  connection matrix is written to .mpo file (text file)
the connection matrix can be edited by user
____________________

Output files: .hau , .pdb, .gjf
Gaussian input file .gjf can be generated

Many .hau files can be easy connect in one system

The picture with the structure:

Left mouse (up-down, left-right): turn the structure in YZ, ZX planes
Left mouse + Shift: turn the structure in XY plane
Right mouse (left-right): change of the size of the structure
              (up-down): change of the size of balls and sticks
Right mouse + Shift: move the structure in XY plane   

Buttons:  XY, YZ, ZX: set the structure position to given plane
          (+/-): slowly move the structure in given plane
          and also (+/-) with Shift, Alt, Ctrl very slow movement

remuneration of the atoms (only in files log, hau):

place the line: renum atoms
and the two columns:
old number  new number
....
