EMP BWEC

Docker installation
The PRIMA software for analysis, simulation, etc. is inside a Docker container. In case you are not running primasoft in any of EMP's pc's, then first you will need to install Docker. Check how to do it here:

• Install Docker Engine for Ubuntu
• Install Docker Desktop for Windows
• Install Docker Desktop for Mac
• Youtube video concerning Ubuntu Installation\

Git clone the image
Now you need to pull the Docker image from the EMP GitLab repository. Open a new terminal, and do:

git clone https://gitlab.rlp.net/emp/primasoft.git

Start the container
Before starting the proper docker container, you need to add your personal user into the docker group. For that, do:

usermod -a -G <user> docker

After that, you will need to 're-enter' into your user session to make sure your user is now inside the docker group. For doing this, you can always restart the computer, or type in a terminal

 
su <user_name>

and then write

groups

Once you type that, you should be able to see all groups your user is in, so the docker name should appear there.

Starting the container and testing the simulation
Now you need to start the container so you can run the full primasoft. Write:

$ cd primasoft
$ ./start_run.sh

A new container with the name primaSoft-dev should be created. After running ./start_run.sh The output should look like this:

./start_run.sh
The default directory for G4WORKDIR is /home/foski/geant4_workdir. You can change it by adding -DG4WORKDIR=${Your_Host_Dir} to run this script.
access control disabled, clients can connect from any host
starting new container with name primaSoft-dev...

The last line means your are already inside the container under the ubuntu username.

source ./setenv.sh
cd utils/
make
cd ~/primasoft/analysis
mkdir lib
make

cd ~/primasoft/geant4
make

geant4$ primag4sim primag4sim.conf

Rootmacros
In order to execute rootmacros, the include paths need to be set.
This can be done automatically with a rootlogon.C file.
Create the rootlogon.C file:

$ cd ~/
$ mkdir .rootlogon
$ geany .rootlogon/rootlogon.C

Enter the following lines to your rootlogon.C file:

// This is the file rootlogon.C                                                 
{
  printf("\n Beginning new ROOT session\n");

  gROOT->ProcessLine(".include your_path/primasoft/geant4");
  gSystem->Load("<geant4_workdir>/tmp/Linux-g++/primag4sim/libprimadict.so");                              
}

Here, your_path is the path to the primasoft git repository and the <geant4_workdir> can be found out by $ echo $G4WORKDIR.

Now root needs to know where to find the rootlogon.C file. Therefore in ''$FAIRSOFT_BUILD_DIR'/share/root/etc/system.rootrc' change the line:

Rint.Logon:    rootlogon.C

to:

Rint.Logon:    ~/.rootlogon/rootlogon.C

Now you can execute the rootmacro:

/geant4$ root -l rootmacros/test.C+
