I am going to suggest chapters and possibly sections (an outline) for the MOLLER GEANT4 documentation. People will need to provide the text for the different sections. People should also feel free to suggest a different outline or set-up.

Getting Started
Getting the simulation
In a terminal window, type:
- svn checkout https://jlabsvn.jlab.org/svnroot/moller12gev
Get the field maps:
- -OR- link to some central location, on the farm machines:
- The defaults are currently (both in cylindrical coordinates):
- ln -s /w/halla/parity/disk2/jmammei/tosca_stuff/MAPFILES/blockyHybrid_3.0.txt fieldmap_back.txt
- ln -s /w/halla/parity/disk2/jmammei/tosca_stuff/MAPFILES/blockyUpstream_1.1.txt fieldmap_front.txt
- ln -s /w/halla/parity/disk2/jmammei/tosca_stuff/MAPFILES/blockyHybrid_3.0.txt fieldmap_back.txt
Setting the environment variables
You'll have to make sure your environment variables are set correctly. If you are running the simulation on your
own machine, for now you'll have to set the environment variables yourself, but be sure to also change the version of
GEANT in the local_moller_settings.dat file.
- On ifarml1 or ifarml6, type:
- source env_jlabcue
Batch Mode
To run in batch mode:
- Create a scratch directory in your home directory with a link to a ROOTfiles directory
- Create your own .mac file or modify (or modify/use run_ee.mac, run_ep.mac or run_ine.mac)
- Type, for example: bin/Linux-g++/moller_sim run_ee.mac
Note: The default .mac files are intended to run on the farm using jsub, but to test you can change the number of
events to 10k instead of 100k, for example.
Interactive Mode
Running on farm
Run it:
Create a scratch directory in your home directory with a link to a ROOTfiles directory somewhere
Create your own .mac file or modify (or modify/use run_ee.mac, run_ep.mac or run_ine.mac)
Type: bin/Linux-g++/moller_sim run_ee.mac
Look at output
From moller12gev directory:
- If you haven't compiled the analysis code yet:
- cd analysis
- make
- cd ../
- Then:
- Modify sample.ini file in the analysis/initfiles directory to have the name(s) of the rootfile(s)
- From terminal: ./analysis/mollerClass analysis/inifiles/sample.ini
- The output and plot files should be created in your output/ and plots/ folders
- Modify sample.ini file in the analysis/initfiles directory to have the name(s) of the rootfile(s)
- --> see more details in the README file
