Implementing an interactive web-based DAS client

Abstract

The Distributed Annotation System (DAS) allows clients to access many disperse genome and protein annotation sources in a coordinate manner. Here we present DASGenExp, a web based DAS client for interactive visualisation and exploration of genome based annotations inspired in the Google Maps user interface. The client is easy to use and intuitive and integrates some unique functions not found in other DAS clients: interactivity, multiple genomes at the same time, arbitrary zoom windows,... DASGenExp can be freely accessed at http://gralggen.lsi.upc.edu/recerca/DASgenexp/. © 2009 Springer-Verlag Berlin Heidelberg.
