Many tools are available for the simulation of ILC detectors and the analysis of results. There are three differents toolchains that can be used. These have been developed separately in the US, European, and Asian (Japanese) regions., corresponding to the LDC, SiD, and GLD detectors. The software suites corresponding to the first two detectors can simulate all 3 detector concepts, so there is no strict division on which tools should be used for a certain detector study.
The ALCPG and SLAC use The system used by SLAC and ALCPG has the SLIC Simulations Package (C++) with the org.lcsim for reconstruction and analysis using Java. This system also uses the JAS3 graphical analysis environment. Much of the functionality within org.lcsim comes from the FreeHep Java Library.

for information about the user interface directory or command. Of course, this requires that the programmer actually put in some useful help string. Most commands and directories have such information.
How do I run a macro containing UI commands?
You can put Geant4 UI commands into one or more macro files that slic can execute. This is done with the "-m" switch. There can be any number of these switches given to slic at the commandline. For instance, this command will execute the two macros init.mac and run.mac.mac and run.mac.
| No Format |
|---|
slic -m init.mac -m run.mac
|
The macros are executed in the order given at the command-line.
If macros are interspersed throughout the command switches, then SLIC will also execute each command in order.
| No Format |
|---|
slic -m init.mac -x -o output -p myDir -m run.mac |
The macros are executed in the order given at the command-lineFirst init.mac will be executed. Then the three commands corresonding to the "-xop" switches and finally run.mac presumably executes the /run/beamOn command.
How do I run in interactive mode?
SLIC can be started in interactive mode using the "-n" option option or the /control/interactive UI command.
This command will start Geant4 in PreInit mode where the geometry is not loaded.
...
| No Format |
|---|
slic -g myGeom.lcdd -n |
The LCDD file will be constructed, so the simulator will start in Idle mode.
What is a typical command to run SLIC in batch mode?
...
The BeginEvent and EndEvent markers are the best indicators of the job's progress.
Most batch systems will provide logging services, and the tail command can be used on these files, too.
How do I run SLIC on the LSF batch system?
The bsub command is used to run SLIC on LSF.
