If you built and installed Geant4 configured with the option
GEANT4_INSTALL_DATA
set, then the Geant4 dataset
libraries will also be downloaded and installed.
In this case, the geant4.(c)sh
and
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 choose not to install the datasets, but require them later, you will need to download and unpack them by hand to a location of your choice and set the needed environment variables:
G4ABLADATA
Set to the path to the G4ABLA3.0 dataset.
G4LEDATA
Set to the path to the G4EMLOW6.23 dataset.
G4LEVELGAMMADATA
Set to the path to the PhotonEvaporation2.2 dataset.
G4NEUTRONHPDATA
Set to the path to the G4NDL4.0 dataset.
G4NEUTRONXSDATA
Set to the path to the G4NEUTRONXS1.1 dataset.
G4PIIDATA
Set to the path to the G4PII1.3 dataset.
G4RADIOACTIVEDATA
Set to the path to the RadioactiveDecay3.4 dataset.
G4REALSURFACEDATA
Set to the path to the RealSurface1.0 dataset.
