INTRODUCTION

JWeb is a graphical point-and-click user interface for displaying and interacting with SPIDER images developed at the Resource for the Visualization of Biological complexity (RVBC) located in the Wadsworth Laboratories, Albany, New York. JWeb is written in "JAVA" using Java Advance Imaging (JAI) and runs under the LINUX, WINDOWS and IRIX systems. JWeb was developed by Dr. Bimal Rath and contains more than 16,000 lines of code.

OVERVIEW

To visualize and analyze SPIDER images using JWeb, the implemented operations have been divided into three categories e.g.
    1) operations permitted on a single image
    2) operations permitted on a set of images
    3) operations permitted on a volume
The relevant available operations are accessible after the desired image or image series or the volume is opened.

The opening GUI of JWeb contains menus to open a 2D image, or a series of 2D images or a volume. Output message window is also contained within it.

Two different kinds of parameter settings have been implemented in JWeb. One is, "Global Settings" and the other is "Local Settings". By using the "Options" menu in the opening GUI of JWeb, "Global Settings" can be set. As a result of which, all images displayed there after will have the same size and same contrast range. However, each image object will have an EDIT menu which can be used to override the global settings.

In most cases, in a JWeb GUI, when a desired option is selected by clicking on a check box or clicking on a radio button, the relevant sub-options are enabled and the rest are disabled.

OPERATIONS

As described earlier, the Operations are grouped under 3 main categories: Image Operations, Image Series Operations, Volume Operations,
