Converting Compact Descriptions to LCDD

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.

1. Follow the instructions in Building+org.lcsim+software to build the GeomConverter package.
2. Go to the GeomConverter directory and build a distribution.

   maven dist
   

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

   cd ..
   tar -zxvf GeomConverter/target/GeomConverter-0.3.tar.gz
   

4. Run the compact to LCDD converter.

   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.

slic -g det.lcdd -z -n
