*******************************************************************

Thank you for downloading PDBViewer. This is a small viewer written 
as part of my Final Year University Project.  It aims to provide 
some of the basic viewing options required when analysing PDB files.

Many features I wanted to add were beyond the scope of this project, 
but I hope to have improved on some of the features present when 
compared to other PDB viewing packages.

Please email me at cusimar9@hotmail.com for any comments
or bugs found.


INSTRUCTIONS
------------

General Use
-----------

Use the LEFT mouse button to rotate the molecule
Use the RIGHT mouse button to zoom in and out
Use the MIDDLE button to select an atom and display its information


File menu
---------

Select a pdb file to view.


Options Menu
------------

Autoselect Settings -> Autoselect best settings for large molecules
- This will automatically select the lowest graphical settings for
- molecules greater than 30,000 atoms. Recommended.

Autoselect Settings -> Disable high quality settings for large molecules
- This will not allow the user to accidentally select graphical settings 
- for large molecules (greater than 50,000 atoms) which may be too slow 
- to render. Recommended.

Draw multiple bonds
- Will represent multiple bonds correctly if selected, otherwise will
- show all bonds as single

Highlight PDB Conect bonds
- Will highlight bonds defined explicitly in the PDB

Colour by chain
- Will colour the different chains in the molecule

Colour by residue
- will colour the different residues in the molecule

Draw unbonded atoms
- Selects these to be rendered or not

Bond Accuracy
- In most cases the lowest setting provides correct results, however
- a better setting may be chosen if desired


Render menu
-----------

Draw Atoms
- How to represent atoms in the molecule. NOTE 3D atoms are particularly
- detrimental to system performance

Draw Bonds
- How to represent bonds in the molecule

Draw CPK Space Filled
- Represent the molecule as CPK Space Filled

Change Line Width With Distance
- When drawing the molecule as lines rather than in 3D, this will give the
- illusion of lines being thicker the closer you are, giving some illusion
- of depth.

Detail for 3D
- Change the detail for 3D rendering


Navigation menu
---------------

Spin
- Automatically rotate the molecule

Speed
- Selects the speed at which the Spin, rotation and zoom of the molecule occur

Move Molecule
- When this option is selected the molecule may be physically moved relative
- to the eyepoint, rather than just rotated.  This makes it easier to zoom
- in to a particular point of the molecule.

Center Molecule
- Re-centers the molecule

Help
- Print a list of common commands
