Project template

Using the Project template

FairRoot deliver meanwhile a project template that can be used as a starting point for anybody who would like to build simulation and reconstruction on FairRoot. The project Template is in the FairRoot/template/project_template directory

The template demonstrate and implement the following:

1. General structure of the software (cake config files, VMC/Geant configurations, etc ..)
2. Example detector with sensitive and passive volumes (NewDetector) and data class
3. Particle Stack for Geant3/4 with filtering infrastructure
4. Event generators (Pathia6,8) more are available directly from FairRoot
5. Passive component implementation (Magnet Yoke, Beam Pipe)
6. Track visualisation tool (Event display)
7. A rename script which replace all the generic names to user defined ones

Step by Step installation

1. Install FairSoft

   we use here "fair_install" as a directory name, you can use what you went!

   mkdir ~/fair_install
   cd ~/fair_install
   #git clone https://github.com/FairRootGroup/FairSoft.git
   git clone -b dev https://github.com/FairRootGroup/FairSoft.git
   cd FairSoft
   ./configure.sh
   # 1) gcc (on Linux) 5) Clang (on OSX)
   # 1) No Debug Info
   # 2) Internet (install G4 files from internet)
   # path: ~/fair_install/FairSoftInst

2. Install FairRoot

   # Set the shell variable SIMPATH to the installation directory
   export SIMPATH=~/fair_install/FairSoftInst
   [setenv SIMPATH ~/fair_install/FairSoftInst]
   
   cd ~/fair_install
   git clone -b dev https://github.com/FairRootGroup/FairRoot.git
   cd FairRoot
   mkdir build
   cd build
   cmake -DCMAKE_INSTALL_PREFIX="~/fair_install/FairRootInst" ..
   make
   make install

   To run the tests do:

   # To run test: make new shell, do not define SIMPATH
   cd ~/fair_install/FairRoot/build
   make test

3. Install the template:

   you need to copy the [project template] (https://github.com/FairRootGroup/FairRoot/tree/dev/templates/project_template)to you own directory

   # Set the shell variable FAIRROOTPATH to the FairRoot installation directory
   export FAIRROOTPATH=~/fair_install/FairRootInst
   [setenv FAIRROOTPATH ~/fair_install/FairRootInst]
   
   cd ~/fair_install
   cp  -rf  FairRoot/templates/project_template   MyTest
   cd MyTest
   ./rename.sh  MyExperiment  PREFIX  MyDetector 
   
   # Please call the script with three parameters. The first one is the
   # name of the project. The second one is the prefix in front of
   # the class names. and some directories. So this second parameter
   # shouldn't be to long. The third parameter is the name of the
   # detector you want to implement.
   # As an example the if you want to create a project for the Panda
   # experiment and you want to implement a Straw Tube Tracker (stt)
   # you would call the script in the following way.
   # ./rename.sh Panda Pnd stt
   
   cd ..
   mkdir build
   cd build
   cmake ../MyExperiment 
     make
   . config.sh    [or source config.csh]

   Now you can for example simulate some events and run the event display:

   root -q ../MyExperiment/macro/run_sim.C
   root ../MyExperiment/macro/eventDisplay.C
   // Click on "FairEventManager" (in the top-left pane)
   // Click on the "Info" tab (on top of the bottom-left pane)
   // Increase the "Current Event" to >0 to see the events
   root [1] .q
