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.
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.
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.
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.
JAS3 on OSX
On OSX you may need to execute export AWT_TOOLKIT=XToolkit in your environment for the GUI to work correctly. This command can be put into your Bash shell profile to run every time you login.
Next a set of plugins needs to be installed. Open View > Plugin Manager and make the following selections:
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.
