[Gate-users] Error running benchmarks

[Marc Chamberland]

First, figure out if you're using the bash or the csh (or tcsh) shell by typing the following on the command line:

echo $0

For the bash shell, you'll want to edit .bashrc; for csh or tcsh, you'll want to edit .cshrc. Then, from your home folder on the command line, you can type the following to make sure that the file exists:

ls -a

It should show all the files in this folder, including .bashrc (or .cschrc). If it does not exist, you can create it in your favourite text editor. Make sure to save it as .bashrc (or .cshrc) with no additional extension.

Open .bashrc (or .cshrc) with your favourite text editor. Make any appropriate changes. For example, you could add the following line if it is not already there:

source /path/to/geant4/bin/geant4.sh

Save and close the file. From the command line, make sure to re-source the .bashrc (or .cshrc) file to take the changes into account:

source ~/.bashrc


Hope this helps.

Marc

I didn't do the g4 data on option when I installed geant4, so I have to manually add paths to the data libraries. And how exactly do I modify the  .bashrc file, I have an amateurish knowledge of Linux.

Hi Felix,

G4LEDATA should be set when you source Geant4 (with the geant4.sh or .csh script).

Make sure to run the following command before launching Gate:

source [path to Geant4 installation]/bin/geant4.sh (or .csh)

Usually, you would include that line in your .bashrc or .cshrc file, so that you don't have to do this step manually every time.

You may also want to check the script and make sure that it is defining G4LEDATA correctly.

Does anyone know what can cause the following error:

Environment variable G4LEDATA not defined

It is generated after running the benchmarkPET.mac
