These images were created within PREPI. It is important to note that
these images can be MANIPULATED INTERACTIVELY within PREPI. 
These images are not intended to cover all PREPI features but simply
to give an general idea of program features. The movies were made by
simple auto screen captures within PREPI. In addition PREPI can also
produce Raytraced Images (via use of the program POVRAY).

1) 5PTI - C-alpha backbone / Planes / Disulphide Bridges
    This example illustrates display of C-alpha backbone
    with TYR & PHE side chains shown as Disks and Disulphide
    bridges.

2) 5PTI - Ribbon / Hetro-atoms / Disulphide Bridges
    This example illustrates Ribbon display, Disulphide bridges
    and hetro atoms.

3) 5PTI - Cylinder & Arrow / Disulphide Bridges
    This example illustrates display of helices as Cylinders
    and sheets and arrows.

4) 5PTI - VDW Spheres
	  
5) 4HHB - Cylinder & Ellipsoids / Transparency
    This example illustrates display of inertial ellipsoids, transparency,
    helices as Cylinders and Heme as spheres.

6) 2CRD - NMR structure Averaging
    Cylinderical ribbon and ellipsoidal representations.

7) 4ECH - NMR structure Averaging - Cylinder Colouring
    Cylinderical ribbon with colouring.

8) 3CRO - DNA-PROTEIN Complex
    DNA as Ribbon + Ladder and protein as Cylinders + Coil

9) Virus Structure Model
    Protein - Lipid Model
    Built using PREPI FREE FORMAT file structure (also see animation)


10) Least squares fitted surface - 6LDH sheet
     Least squares fitted surface - 1GOX beta-barrel
    Part of PREPI's Least squares surface (lines,planes,conics,quadrics) fitting options

SOME MOVIES CREATED BY PREPI


The images were created and saved by PREPI. However they have been converted
to 8-bit GIF format. So the quality is much lower than that originally output
by PREPI. These were created by simple (and automatic) screen capture.

SMALL PROTEIN - 5PTI Trypsin inhibitor

DNA-PROTEIN - 3CRO 434 Cro protein

DNA-PROTEIN - 1LCC Lac repressor headpiece

NMR STRUCTURE - 2CRD Neurotoxin - Charybdotoxin

VIRUS MODEL  - Built using prepi free format

POLYGON  - Built using prepi free format
