Overview

The SLIC simulator package uses a low-level XML data format while the reconstruction uses a smaller, more targetted format called the "compact description". Using a compact geometry in the simulator requires converting it to LCDD first.

Building and Running GeomConverter

1. Follow the instructions in Building+org.lcsim+software to build the GeomConverter package.
2. Run the application

   No Format
   maven run

   which will display This command displays a simple GUI for running the application where the target format can be selected along with the Input and Output files.

Building and Running a GeomConverter distribution

1. Go to the GeomConverter directory and build a distribution.

   No Format
   maven dist

2. Unzip the distribution from one directory below the current one. (This example has a hardcoded version number.)

   No Format
   cd .. tar -zxvf GeomConverter/target/GeomConverter-0.3.tar.gz

3. Run the compact to LCDD converter using the script.

   No Format
   GeomConverter-0.3/bin/GeomConverter compact.xml det.lcdd

   The output LCDD file can be used as input to SLIC, which might look like this. No Format slic -g det.lcdd -z -n

Command Syntax

If no output file is specified the GUI will be displayed. If no format is given the format will be guessed based on the output file.

Running in SLIC

The output LCDD file det.lcdd can be used as input to SLIC, which might look like this.

slic -g det.lcdd -z -n
