Abstract
Recent sequencing of genomes of several microorganisms provides an opportunity to have access to huge volumes of data stored in various databases. This has resulted in the development of various computational and visualization tools to aid in retrieval and analysis of data. Development of user friendly genome data mapping and visualization tools facilitates researchers to closely examine various features of genes and make inferences from the displayed data efficiently. PGV – Prokaryotic Genome Viewer is a Java based web application tool capable of generating high quality interactive circular chromosome maps. With simple mouse roll over tasks on the interested region on the displayed map, the user is provided with features such as feature labeling, multi-fold zooming, image rotation and hyperlinking to different information resources. The tool is capable of instantaneously generating maps using user-supplied sequence data.
