OpenAstexViewer is a Java molecular graphics program that assists in structure based drug design. It can be used as an Applet in a web page or as a desktop application. The software should run on most operating systems and in most internet browsers.
OpenAstexViewer provides support for extending the scripting language with arbitrary commands. This document covers an example of this.

The view of the molecule that is loaded can be controlled using the mouse. The interface is similar (but not identical to) a number of other molecular graphics programs. In general only the left mouse button is used for controlling the view, as the right mouse button is reserved for bringing up the popup menu when OpenAstexViewer is running as an applet.

OpenAstexViewer has a more powerful graphical interface than the first version, which was principally intended for use as a preconfigured Applet running in a web page. The graphical user interface allows most operations to be carried out without the need for writing scripting language. This document provides a quick tour of the user interface, and then a few step-by-step guides for carrying out common operations.

OpenAstexViewer Features:
1. Sphere, cylinder and stick display styles for molecules.
2. Versatile labelling and distance monitors.
3. Shaded molecular surfaces, with transparency and property mapping.
4. Protein schematics and secondary structure assignment.
5. High quality image production to arbitrary resolution, with antialiasing and shadows.

Requirements:
* Internet Explorer
