Installing JAS3

Java Analysis Workstation 3 (JAS3) is a graphical workbench application that can be used for viewing and manipulating AIDA histograms, viewing event displays, and looking at basic information contained in LCIO files.

Getting the Distribution

You can download the latest distribution from the download area either by clicking the links and using the browser or executing a command like this.

wget http://java.freehep.org/maven2/org/freehep/jas-assembly/3.1.0/jas-assembly-3.1.0-distribution.tar.gz

The above command is just an example.  In general, the current distribution should be used.

Installing the Distribution

Once the tarball is downloaded, you can unpack it with a Unix command.

tar -zxvf jas-assembly-3.1.0-distribution.tar.gz

This will create the directory jas-assembly-3.1.0 which is the root directory for running JAS.

Running JAS

Finally, you can simply run JAS from the command line using a simple command such as the following.

 ./jas-assembly-3.1.0/jas3

You should now see the GUI load.

Configuring Plugins

Next we need to install the plugins used for analyzing HPS data.

In the View menu, click on the Plugin Manager item.

Installing the Plugin from HPS Java

In order for JAS3 to load the HPS jar files, the plugin module should be installed.

svn co svn://svn.freehep.org/hps/java/trunk/plugin hps-plugin
cd hps-plugin
mvn install

When you have made local changes to HPS projects, the plugin module should be re-installed so that JAS3 picks up the changes.
