Along with other software for LCD research, a common distribution of the
SLIC simulator package is available for SLAC NFS users.

If you need access to SLAC NFS, contact unix-admin@slac.stanford.edu. |
From a Unix terminal, open a connection to noric-new and login.

You need to setup the project environment to access the common software
distribution.

Now, you should be able to run slic from $PRJ_BIN.

There are a number of different ways to run SLIC, including purely
macro or command-line driven.
For instance, here is a command to load the SDJan03 test geometry
and start an interactive terminal.
| No Format |
|---|
slic -g $PRJ_DIST/slic/current/examples/sdjan03/SDJan03.lcdd -z -n |
Now, in order to have a work area for your SLIC usage, checkout the
package from CVS.
| No Format |
|---|
export CVSROOT=:pserver:anonymous@cvs.freehep.org:/cvs/lcd cvs co slic cd slic |
Within this directory, you will be able to write LCIO files.
This is an example of visualizing a single muon event in the SDJan03 test
detector using GPS. From your slic directory, execute the following
commands.
| No Format |
|---|
slic -g examples/sdjan03/SDJan03.lcdd -z -n Idle>/control/execute macros/vis_gl.mac Idle>/control/execute macros/gps.mac Idle>/run/beamOn |
You could also dump a heprep.
| No Format |
|---|
Idle>/control/execute macros/heprep2.mac |
Or you may want to check for overlaps in the detector.
| No Format |
|---|
Idle>/geometry/test/recursive_test |
A purely macro-driven job can be executed from the slic directory like so.
| No Format |
|---|
slic macros/sdjan03_dbg.mac |
You can dump this event using an LCIO utility.
| No Format |

In general, a minimalist SLIC session will be started as follows.
| No Format |
|---|
slic -g /path/to/geometry/file -z -n |
The -z option tells SLIC to initialize the simulator at that
point and -n will start an interactive session.
| Tip | ||
|---|---|---|
| ||
SLIC must be initialized directly by the user, either by executing |
Alternately, you may start in interactive mode and manually input
all required commands.
| No Format |
|---|
slic -n Idle>/lcdd/setURI examples/sdjan03/SDJan03.lcdd Idle>/run/initialize |
An input StdHep file can be specified with the -i option or
using the /stdhep/setFile command from the PreInit> prompt.
When you call /run/beamOn, the events from this file will
be used as input to the simulator.
