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:
support_jalview@bartongroup.org by Friday 19th October 2018.

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

Get the latest Jalview desktop application:

  • Alternately, download an installer for your system from the InstallAnywhere Jalview Installers page.
    InstallAnywhere is a Java program installation system. It will work out which operating system you have, and present you with the package it considers most appropriate. You can download the Jalview application installation on its own, and optionally download a copy of the Java Virtual Machine which actually runs Jalview.

Installing on OSX

We recommend you install the jalview desktop via the signed OSX disk images: Install Jalview + Java or Install Jalview only (Works on Sierra if you download Java separately). It is also possible to launch Jalview on OSX via Web Start, but you will first need to either modify your GateKeeper security settings (see the FAQ entry), or open a Terminal and enter:

javaws http://www.jalview.org/webstart/jalview.jnlp

This works because webstart launches from the commandline appear to bypass the GateKeeper security warning about "unknown developers".
Problems?  Take a look at the FAQs.

If you are interested in the source, then we'd also recommend you take a look at the Development section of the website, which includes information about building Jalview from source, and developing with Jalview.

More about running the Jalview application

If you don't have Java version 1.6 or later, first install Java on your machine from from the Java Download Site. Then click on the Install link above.

If your browser hasn't been set up to run Java WebStart JNLP files, the Start link above will download a file called jalview.jnlp. Some browsers will ask you what you want to do with the JNLP file (instead of automatically downloading it somewhere, or presenting it to you as text). If a dialog appears with "Open using application..." on it, use the javaws application to run your file (and check the box marked "Don't ask me again"):

  • <path to java runtime installation>/bin/javaws
  • <path to jdk installation>/jre/bin/javaws
  • javaws.exe

If you think that your browser should really be working with Java properly, you can test it at www.java.com. If things really are not working, use the InstallAnywhere version of Jalview.
