Visually, Dasty provides numerous advantages over other DAS clients. Space is used effectively so there is no need to scroll in portions of the screen. It makes use of the standard colours employed by Uniprot and SRS for annotations. Dasty uses colours, borders, complimentary shades and separating lines to contrast features with the background and to make the relationships among annotations clear. Finally, Dasty allows grouping and sorting of annotations by various properties, and zooming within a protein sequence.
Dasty3 is based on a plug-in architecture. It emphasises extendibility, plug-in customisation, and interoperability –e.g. data exchange amongst plug-ins. The architecture also makes it easy for developers to integrate Dasty3 into existing Web applications as well as to configure the look-and-feel by defining customised templates.
