Acts Common Tracking Software

ACTS version 37.4.0 https://github.com/acts-project/acts/tree/v37.4.0

Step by step instruction:

Clone repo

git clone https://github.com/OlivierSalin/Faser2_acts.git acts_faser2 cd acts_faser2 git clone https://gitlab.cern.ch/acts/OpenDataDetector.git thirdparty/OpenDataDetector

Install all dependencies if access to cvmfs

source CI/setup_cvmfs_lcg.sh

If this does not work directly use those command line

EL9: /cvmfs/sft.cern.ch/lcg/views/LCG105/x8664-el9-gcc13-opt/setup.sh \ Centos7: /cvmfs/sft.cern.ch/lcg/views/LCG105/x8664-centos7-gcc12-dbg/setup.sh

Build

``` cd .. cmake -B acts-build -S actsfaser2 \ -GNinja \ -DCMAKEBUILDTYPE=RelWithDebInfo \ -DCMAKEINSTALLPREFIX="acts-install" \ -DACTSBUILDODD=ON \ -DACTSBUILDFATRAS=ON \ -DACTSBUILDFATRASGEANT4=ON \ -DACTSBUILDEXAMPLESDD4HEP=ON \ -DACTSBUILDEXAMPLESGEANT4=ON \ -DACTSBUILDEXAMPLESPYTHIA8=ON \ -DACTSBUILDEXAMPLESPYTHONBINDINGS=ON \ -DACTSBUILDPLUGINDD4HEP=ON \ -DACTSBUILDPLUGINEDM4HEP=OFF \ -DACTSBUILDPLUGINGEANT4=ON \ -DACTSBUILDPLUGINFPEMON=ON \ -DACTSBUILDPLUGINJSON=ON \ -DACTSBUILDPLUGINTGEO=ON \ -DACTSFORCEASSERTIONS=ON \ -DACTSENABLELOGFAILURE_THRESHOLD=ON

cmake --build acts-build --target install -j4 ```

ACTS needs to be source before each use: cd acts_faser2 source CI/setup_cvmfs_lcg.sh source acts-install/bin/this_acts.sh source acts-install/python/setup.sh Or you can directly use the bash script cd actsfaser2 source Setupacts.sh

Setup can be testied using this tutorial examples if bug contact me: olivier.salin@cern.ch cd .. python acts_faser2/Examples/Scripts/Python/truth_tracking_kalman.py python acts_faser2/Examples/Scripts/Python/truth_tracking_telescope.py python acts_faser2/Examples/Scripts/Python/truth_tracking_Faser2.py

More information can be found in the Acts documentation.

Repository organization

The repository contains all code of the Acts projects, not just the core library that a physics experiment is expected to use as part of its reconstruction code. All optional components are disabled by default. Please see the getting started guide on how-to enable them.

• Core/ contains the core library that provides functionality in the Acts namespace.
• Plugins/ contains plugins for core functionality that requires additional external packages. The functionality also resides in the Acts namespace.
• Fatras/ provides fast track simulation tools based on the core library. This is not part of the core functionality and thus resides in the separate ActsFatras namespace.
• Examples/ contains simulation and reconstruction examples. These are internal tools for manual full-chain development and tests and reside in the ActsExamples namespace.
