Revision as of 11:24, 25 January 2011

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.

Overview

GEANT4

MOLLER

DOxygen Documentation

Getting Started

Getting the simulation

In a terminal window, type:
svn checkout https://jlabsvn.jlab.org/svnroot/moller12gev

Get the field maps:
Proposal: upstream, hybrid
Default: upstream, hybrid

-OR- link to some central location: /w/halla/parity/disk2/jmammei/tosca_stuff/MAPFILES/
use the README file to decide which maps to use; the defaults are currently:
blockyHybrid_3.0.txt and blockyUpstream_1.1.txt (both in cylindrical coordinates)

Setting the environment variables

You'll have to make sure your environment variables are set correctly.

On ifarml1 or ifarml6, type:
source env_jlabcue

If you are running this on your own machine, you'll have to set the environment
variables yourself, and change the version of GEANT in the local_moller_settings.dat file.

Batch Mode

Interactive Mode

Running on farm

cd moller12gev
source env_jlabcue
make

Run it:

Create a scratch directory in your home directory with a link to a ROOTfiles directory somewhere

Create your own .mac file

*** example.mac ***
/moller/gun/gen 0
/run/beamOn 1
*******************

Create your own .csh file

*** example.csh ***
#!/bin/csh

source env_jlabcue
use root
bin/Linux-g++/moller_sim run_juliette_test.mac

exit
*******************

Execute the .csh file from command line

Look at output

cd analysis
make
cd ../
Create a plots and output folder
Create a .ini file in the analysis/initfiles directory

*** example.ini ***
[General]
outdir=plots/juliette_test_
rootoutfile=output/juliette_test.root
num_thrown=100000
eventtype=2
plottype=.gif

[Filenames]
file1=/u/home/crowder/scratch/ROOTfiles/moller_100913_143618.root
*******************

From terminal: ./analysis/mollerClass analysis/inifiles/example.ini

The output and plot files should be created in your output/ and plots/ folders

--> see more details in the README file
