iLat Desktop Installation (preliminary)

Notice: The Fermi code has not been released to the public and is for use by members of the LAT Collaboration only!

Caveat: This section should be considered preliminary documentation of the setup required to run iLat from your desktop computer. However, you will not be able to use iLat to retrieve LAT data. The examples given have been vetted by Andrea Tramacere, but have not yet been thoroughly tested.

Note: Please copy Andrea Tramacere and Gino Tosti regarding any problems you may encounter.

Troubleshooting Tip: If you experience a timeout problem when running iLat from home, or from a non-SLAC facility, Bryson Lee reported a similar problem after switching from his old Belkin router to a LinkSys WRT54G and fixed it by adding the following setting to his .ssh/config file on his home system:

Host *
ServerAliveInterval 240


You are running iLat on a Unix machine.

Note: While directory names and corresponding paths used below are intended as examples only, it is assumed that any changes you may prefer will be used consistently throughout this exercise.


  • SSH2
  • Access to the CVS repository, or have a copy of the iLat root directory.
See: Prerequisites: Running iLat on a Unix Desktop Machine

Desktop Setup

  1. Install iLat in, for example: /u1/iLat. The CVS command to install iLat is:

    cvs co iLat

Note: It is assumed that

  1. Install ScienceTools (v9r7, or above) in, for example:


  2. Install the external libraries in, for example:


  3. Set up your bash.rc to include:

    export GLAST_EXT=/u1/ST/externalLibs
    export ST=/u1/ST/
    export PATH=$PATH:${ST}/bin
    export INST_DIR=${ST}
    export iLat=/u1/iLat
    source ${ST}/bin/config/
    export PFILES=${PFILES}:${ST}/code/pfiles/
    export ILATROOT=${iLat}
    source $ILATROOT/

  4. You are now ready to run iLat from your desktop.

Note: You will not be able to use iLat to retrieve LAT data, but you should be able to perform all exercises in Part 2: Analysis of 3C454.3 Using iLat (with the exception of Getting LAT Data -- Options 1 and 2).

For access to LAT data, see: Astro Server, or FermiData and Weekly All-Sky Data.
