Solid run

read Up2date GEMC info at http://gemc.jlab.org for installation and tutorial.

There are a couple way to run GEMC. You can always run it on ifarm for batch mode, but interactive mode will be slow because the OpenGL 3D rendering.

To run interactive mode, install it locally. I only tried it with rpm installation on fedora 14.

To install by rpm package, I recommend to used yum repo,

(but fc14 repo has some problem now, so I downloaded those rpm files directly from http://www.jlab.org/12gev_phys/RPMS/fc/11/x86_64/)

After install, run "source /usr/local/jlab_software/init.csh" to setup environment.

run "setenv G4ROOT /usr/local/jlab_software/geant4" (currently a bug, you have to do this to use solenoid field.

put a copy of solenoid_babar.dat at /usr/local/jlab_software/geant4/data/

get the gcard files for solid at svn "database_io/halla12/solid/geometry". solid_PVDIS.gcard for everything of PVDIS setup, solid_baffle.gcard for just baffle.

Now you are ready to run GEMC with Solid "gemc -gcard=solid_PVDIS.gcard -DATABASE=user_geometry -HALL_FIELD=solenoid_babar"

use option -geometry=1000x1000 to get larger screen instead of default 600x600

use -EXEC_MACRO=slice.vis to see the cut-half plot. (The slice.vis and other macros are not included with rpms, get them at svn /macros/)

for full options, use --help with gemc
