For those urgently needing JABAWS services - please add this temporary server URL to your 'Webservices' preferences

Web service preferences are accessed via your Jalview Preferences (in the Tools menu) - once you've opened the preferences dialog, select Web Services and 'New Service URL'.

We're hoping the JABAWS services will resume to their normal 100% availability later on today.

Jalview is a free program for multiple sequence alignment editing, visualisation and analysis. Use it to view and edit sequence alignments, analyse them with phylogenetic trees and principal components analysis (PCA) plots and explore molecular structures and annotation.

  • JalviewLite is the web based version of Jalview, which is used on many web sites (there's a list of some here)
  • The Jalview Desktop is for biologists and bioinformaticians who need to create, curate, analyse and publish multiple sequence alignments.

Jalview has built in DNA, RNA and protein sequence and structure visualisation and analysis capabilities. It uses Jmol to view 3D structures, and VARNA to display RNA secondary structure. The Jalview Desktop can also connect with databases and analysis services, and provides a graphical interface to the alignment and analysis services provided by the JavA Bioinformatics Analysis Web Services framework.

Finding out more

The About section provides more information, and the links at the top of the page will let you launch the Jalview Desktop, try out the JalviewLite applet demonstration pages. The Download page lets you get a Jalview Desktop installer for your system, and links to compiled jars and source code.


Jalview is an open source project released under the GPL. Its development is coordinated by Jim Procter and Geoff Barton in the Computational Biology group at the University of Dundee, School of Life Sciences with support from the Biotechnology and Biological Science Research Council and the Wellcome Trust.
