Hello, I can access by ssh to Geant4 on /cvmfs/ by this code
source /cvmfs/geant4.cern.ch/geant4/10.6.p02/x86_64-centos7-gcc8-optdeb-MT/bin/geant4.sh
is there something like this for ROOT?
Thank you
Please read tips for efficient and successful posting and posting code

Hi,
There is: you can run for instance
source /cvmfs/sft.cern.ch/lcg/views/LCG_97/x86_64-centos7-gcc8-opt/setup.sh
root
Cheers,
Jakob
Thank @jblomer I tried it but I got error
I also found this one
but you see…I tried so much command but the didn’t work…what should I write?
Moreover, Do I’ve to upload the macro here
/cvmfs/sft.cern.ch/lcg/app/releases/ROOT/6.22.00/x86_64-centos7-gcc48-opt/macros
?
Thank you
EDIT Looking on the ROOT forum I found this message of @Axel
so I tried it and it works (even if it’s an old version of ROOT)
but when I try to upload my macro on
/cvmfs/sft.cern.ch/lcg/app/releases/ROOT/6.09.02/x86_64-centos7-gcc48-opt/root/macros
I can’t do it…so where should I upload my macro?
You are using Windows, do you expect to be able to run CentOS7 binaries?
If not, consider downloading and installing a Windows binary release of ROOT, see https://root.cern/releases/release-62200/#binary-distributions
Hi @Axel I’ve ROOT on my computer (windows distribution). What I mean is:
source /cvmfs/geant4.cern.ch/geant4/10.6.p02/x86_64-centos7-gcc8-optdeb-MT/bin/geant4.sh
but I don’t know where to upload my macro (I can’t upload it on /cvmfs/sft.cern.ch/lcg/app/releases/ROOT/6.09.02/x86_64-centos7-gcc48-opt/root/macros
Try this:
$ /cvmfs/sft.cern.ch/lcg/contrib/gentoo/linux/x86_64/startprefix
Note that you should run the script rather than source it. Inside that environment you will have Geant 10.6.2 and ROOT 6.22, 6.20 and 6.18 with no extra setup required. Cheers,
Thank you the both @axel and @amadio
I runned in gentoo ROOT by the command
root -l
I read there is Geant too. What is the command to lunch Geant here?
Thank you
I am not sure I understand the question. You probably have your own code that uses Geant4. There is no setup required, if you just rebuild your own simulation code, it should use the Geant4 from that environment already. If the code you are using is provided by your institute, then you can use the Gentoo environment just to use ROOT.
@amadio, how does that allow @faca87 to run his script (that sits on his Windows computer) on lxplus? I don’t think your gentoo-prefix is solving anything here - i.e. I believe it’s just adding to @faca87’s confusion 
?
I mean this:
cmake -DGeant4_DIR="C:\Program Files\geant4_10_06-install\lib\Geant4-10.6.1" "C:\B1"
By ssh connection, I’m currently compiling by this code
source /cvmfs/sft.cern.ch/lcg/contrib/gcc/8.3.0/x86_64-centos7-gcc8-opt/setup.sh
source /cvmfs/geant4.cern.ch/geant4/10.6.p02/x86_64-centos7-gcc8-optdeb-MT/bin/geant4.sh
/cvmfs/sft.cern.ch/lcg/contrib/CMake/3.14.2/Linux-x86_64/bin/cmake ../
You wrote
I understand that in gentoo there are both ROOT 6.xx and Geant 10.6.2 and then I asked you the code to compile Geant4 simulation by using this enviroment. Or did I understand wrong?
Exactly @amadio! @Axel I’ve Geant4 and ROOT on my computer but
I need to use Geant4 by ssh connection connecting to the computer hosted in the laboratory because I need to simulate many events, then I can’t simulate by using my own computer (it need so much time!)
Given that I simulate many events, I get a big file ROOT, so I want to analyse them by ssh connection using on line ROOT so that I don’t have first to download the file!
I understand now what you mean. Here’s how I compiled example B1 from Geant4 on lxplus:

You can probably compile in a similar way on your institute’s computer.
