Test that Queue is correctly installed, and that the supporting tools like Java are in your path.


  • Basic familiarity with the command-line environment
  • Understand what is a PATH variable
  • GATK installed
  • Queue downloaded and placed on path


  1. Invoke the Queue usage/help message
  2. Troubleshooting

1. Invoke the Queue usage/help message

The command we're going to run is a very simple command that asks Queue to print out a list of available command-line arguments and options. It is so simple that it will ALWAYS work if your Queue package is installed correctly.

Note that this command is also helpful when you're trying to remember something like the right spelling or short name for an argument and for whatever reason you don't have access to the web-based documentation.


Type the following command:

java -jar <path to Queue.jar> --help

replacing the <path to Queue.jar> bit with the path you have set up in your command-line environment.

Expected Result

You should see usage output similar to the following:

If you see this message, your Queue installation is ok. You're good to go! If you don't see this message, and instead get an error message, proceed to the next section on troubleshooting.

2. Troubleshooting

Let's try to figure out what's not working.


First, make sure that your Java version is at least 1.6, by typing the following command:

java -version

Expected Result

You should see something similar to the following text:

java version "1.6.0_12"
Java(TM) SE Runtime Environment (build 1.6.0_12-b04)
Java HotSpot(TM) 64-Bit Server VM (build 11.2-b01, mixed mode)  

Remedial actions

If the version is less then 1.6, install the newest version of Java onto the system. If you instead see something like

java: Command not found  

make sure that java is installed on your machine, and that your PATH variable contains the path to the java executables.

On a Mac running OS X 10.5+, you may need to run /Applications/Utilities/Java Preferences.app and drag Java SE 6 to the top to make your machine run version 1.6, even if it has been installed.
