If you built and installed Geant4 configured with the option
GEANT4_INSTALL_DATA set, then the Geant4 datasets will have been downloaded and installed automatically.
In this case, the
geant4make.(c)sh scripts will set up the needed
environment variables required by Geant4 to locate these datasets.
On Windows, you will need to set the needed environment variables listed
below by hand. This can be done by opening the Environment
Variables dialog, as described in Section 3.1, clicking on the New button, and entering the Variable name and Variable value using the names and paths described below.
If you chose not to install the datasets, but require them later,
you will need to download and unpack them by hand to the location
you specified for
If you did not set this, it defaults to
Unpacking the datasets in this location will result in Geant4
automatically locating them once
geant4make.(c)sh have been sourced.
If you have datasets in a different location, then you will need to manually set the following environment variables:
Set to the path to the G4EMLOW6.32 dataset.
Set to the path to the PhotonEvaporation2.3 dataset.
Set to the path to the G4NDL4.2 dataset.
Set to the path to the G4NEUTRONXS1.2 dataset.
Set to the path to the G4PII1.3 dataset.
Set to the path to the RadioactiveDecay3.6 dataset.
Set to the path to the RealSurface1.0 dataset.
Set to the path to the G4SAIDDATA1.1 dataset.
