Converting Compact Descriptions to LCDD

Running GeomConverter

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. Run the application

   maven run
   

   which will display a simple GUI for running the application.

Building a distribution

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

   maven dist
   

2. 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
   

3. 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
   

   The full syntax for running GeomConverter is

   GeomConverter-0.3/bin/GeomConverter \[-o format\] \[<infile> \[<outfile>\]\]
   

   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.
