  1. Installing Geant4 Visualization and Analysis Tools using the Workshop CD Geant4 WorkshopSLAC - February 2002 Tony Johnson Joseph Perl

  2. What’s on the CD? • Welcome.html <- Start here • /Geant4.4.0 • Files for installing Geant4 • /Documentation • Geant4 Users Guide, Installation Instructions • Tutorial Overview - Quick guide to running visualization and analysis software • /AdditionalSoftware • Some additional software for analysis, visualization • Each directory on CD has a README.html. • CD is meant to be self-explanatory

  3. Installing Geant4 from the CD • Two methods: • Normal G4 install from source • Beware: • Need to apply all patches yourself • takes 1-n hours to compile Geant4 from scratch • Pre-Compiled G4 • Patches all applied for you • Code is precompiled to avoid need to wait • All source code is included, so still possible to modify flags and recompile/link as necessary

  4. Install G4 from source • You need: • clhep 1.7.0 • geant4.4.0.tar.gz • geant4.4.0.p01.tar.gz • geant4_4_0_p01_VC.zip • additional patch for windows, beware strange internal directory structure • G4HepRep.tar.gz • Patch for visualization with HepRep • T01.tar.gz • Workshop tutorial • JAIDA-G4.tar.gz • Analysis software • All of these files are on the CD. Most in Geant4.4.0/install/ directory. See README.html in that directory for location of CLHEP and AIDA. • I advise applying all patches before initial “make”

  5. Install Pre-Built Geant4 • Three versions available • Windows (95/98/Me/Nt/2000/XP) • self-extracting .exe • Linux (.tar.gz) • egcs-2.91.66 • gcc 2.95.3 • These will probably not work if you have a (significantly) different compiler, but you may still want to start from the pre-built version and do a “make clean” followed by “make” to avoid having to apply all the patches. • Analysis software does not work with gcc 2.96-98 (default gcc on Redhat 7.x). Use a different compiler if possible. • In directory Geant4.4.0/pre-built

  6. Getting started with the T01 tutorial • Once you have installed and compiled Geant4 you can start with the T01 tutorial. • Follow instructions on CD by clicking on “Workshop Tutorial” from welcome page. • T01 instructions include examples of using visualization and analysis • Intended as a quick way to get started • More background information on visualization and analysis during tomorrow’s tutorial.

  7. Visualization - Java and WIRED • Running the visualization part of T01 tutorial will generate .HepRep files. • To view files you need to install: • Java and WIRED • Both are included on the CD, with installation instructions • See John Allison’s talk for OpenGL instructions

  8. Analysis - AIDA • The analysis part of T01 tutorial explains how to use AIDA. • AIDA is an analysis interface that can be used with several different analysis packages (see tomorrow’s talk) • CD includes instructions on installing and running JAIDA – a simple AIDA implementation, plus JAS for offline analysis of .aida files.

  9. What if I don’t have a CD reader? • The CD is accessible at: • http://www-sldnt.slac.stanford.edu/G4CD/ • Only use this if you really have to! • We will post fixes for any problems discovered with the CD at: • http://www-sldnt.slac.stanford.edu/Geant4CD/errata
