210 Lemkin and Thornwall<br />

Fig. 4. Human plasma gel images after the pseudo-3-D transform was applied to both gel<br />

images. The parameter settings for angle and z scale were 15 degrees and 20% respectively.<br />

3.5.5. Other Image Transforms<br />

There are a number of other image transforms which can be invoked. Like the edge<br />

sharpening transforms, the image to be transformed is the one last selected and if<br />

neither was selected (i.e., you clicked on the flicker-window), then both images are<br />

transformed.<br />

4. Notes<br />

1. On installing Flicker on your computer<br />

There are several advantages of running Flicker directly from the NCI Flicker server.<br />

Software updates are completely invisible to users since they don’t have to waste time or<br />

space installing them on their computers. The technique uses existing low cost Web<br />

browser technology that requires little user effort. In addition, it saves time over the alternative<br />

ways that scientists might use to compare 2-D gels and other data. However, if you<br />

are far from our server, want to run Flicker behind a firewall, or want to use it exclusively<br />

on your own data, then it may be advantageous to download Flicker and install it on your<br />

computer (see Subheading 2, step 2b).
