Geant4Py
A set of python modules for using Geant4
System Requirements
CMake
Building system is migrated to CMake system.
Python
Python2.x and Python 3.x (experimental)
Boost
Boost_Python is needed.
(Optional)
ROOT for histogramming/analysis
Tested Platforms
- CentOS7 (RH7 clones)
- OSX (Sierra)
How to Install
Before building library, GEANT4_INSTALL environment variable should be set.
# export GEANT4_INSTALL=<Geant4 install path> (zsh, bash)
# setenv GEANT4_INSTALL <Geant4 install path> (csh)
(G4 install path is the path specified by "CMAKE_INSTALL_PREFIX" when building Geant4)
then
# mkdir build
# cd build
# cmake ..
# make
# make install
By default, g4py is installed in <g4py>/lib(64) directory.
Before doing tests with CTest, you have to set environment variables for Geant4 data.
# make
# make install
# ctest
performs automatic unit/integration tests with CTest.
How to Use:
Some environment variables are required at run time.
PYTHONPATH
Python module search directories, given by a colon-separated list of directories, like
# export PYTHONPATH=<g4py>/lib64:<g4py>/lib64/examples:<g4py>/lib64/tests (zsh, bash)
# setenv PYTHONPATH <g4py>/lib64:<g4py>/lib64/examples:<g4py>/lib64/tests (csh)
Getting started
You can import Geant4Py modules in Python just like
>>> import Geant4
