How do I run Jalview?
You need a computer that can run Java 1.4 or later to run the full Jalview application (at the moment, this excludes Mac OS 9 users and some OSX users who have not upgraded yet – sorry). To download and run the application, go to the download area and follow the instructions there. If you don’t have Java 1.4, but do have Java turned on in your browser, then you can try the applet version of Jalview on the applets page. You can’t use the web services, or save projects, but can at least edit your alignments.
