2D-PAGE Flicker Web Server

Comparing images across the Internet

This is a mirror site for the Flicker Server which is running as part of our web server .

Flicker is a method for comparing images from different Internet sources on your web browser. Scientists around the world often work on similar image data. More of this data is being published on the Internet each year. In the case of 2D protein electrophoretic gel images, maps identifying proteins in these gels are becoming increasingly available. Visually comparing 2D sample gels against these 2D gel database maps may suggest putative protein spot identification in many cases.

The Flicker image viewer is a Java applet which reads two images from the Internet and then displays them in the your web browser. It allows you to enhance them in various ways and to compare them visually in a third window called the flicker window. The program uses the 'flicker method' used in GELLAB (see ref. [1-3]) and Xconf (see ref. [4]). Images may first be enhanced by spatial warping, pseudo 3-Dimensional projections, image sharpening, contrast enhancement and other transforms. The transformed images may then be presented using flickering. Papers describing the details on the Flicker program are given in (see ref. [5-6]) as well as the Flicker Reference Manual.

At present you can flicker compare any two gel images stored at our web server or compare one of these images with an image from a known URL.

WARNING - This implementation of Flicker is still being beta-tested. It is hoped that it will be a fully functional mirror of the Flicker programme in due course.

To Flicker Compare two images:

1. First select a different image for the Left and Right images. This entails a) setting the radio button for the source type and b) selecting the particular image from the scrollable list or typing it directly. You may use any of the three from image sources available for both the Left and Right images. Note: you can only compare different images (not an image against itself).

2. Then press Go Flicker to generate a Flicker comparison of this pair of images.

3. Please WAIT while images load. Depending on the access speed of the web site where the images reside, this may take several minutes.
