Jalview is free to end-users because of support from the UK's BBSRC and The Wellcome Trust

If you would like to see Jalview continue to be available then please take a few minutes to write us a support letter saying how you use Jalview in your research/teaching.

Write as a PDF including your institution's heading and send to:

Thank you all those who have already written such nice letters!

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.

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.
