Genome study requires information pertaining to every gene in a chromosome. Visualising information of how a gene is related to other genes in the same chromosome or to genes in other chromosomes will make the understanding of the relations more clear. Available genome visualization tools provide mainly the view of the overall genome [Websites 2,3,4] and some tools have features like zooming into a particular chromosome and viewing the gene in detail [2].

In this paper we present a new capability of "Genome Vectorizer" (formerly known as "Genome Pixelizer SVG-fied") where a gene can be dragged out of a chromosome for more detailed analysis. This feature is an extension to ‘Genome Pixelizer SVG-fied’ which is a genome visualization tool that has been developed by Elena Kochetkova [1].

"Genome Vectorizer" is a re-designed version of GenomePixelizer, written in 2002 in TCL/TK, a tool that allows for the detection of duplication events in genomes. It capitalizes on the benefits of using XML, XSLT, and SVG technologies combined with JavaScript scripting “to provide users with simpler interface, maximized interactivity; as well as, improved efficiency of genetic data analysis” [1].

Gene dragging capability, which is presented in this paper, will provide users much more interactivity, since often the users focus on a particular gene rather than the entire chromosome. Once the common genes are matched between chromosomes the user can drag the gene of interest out along with all the details pertaining to it.
