org.lcsim is a reconstruction and analysis package for simulation studies for the international linear collider. It is entirely developed in Java for ease of development and cross-platform portabilty. The package is designed to be detector geometry and technology agnostic, so it can be used to work with data for any detector. The package reads and writes data in LCIO format, so can be used with a wide variety of other linear collider software packages.
The org.lcsim software can be used standalone, for running reconstruction and analysis tasks, or can be run inside JAS3 to provide a full interactive analysis toolkit.
Documentation is being developed, for now the best source of documentation is in the linear collider wiki , or you can browse the class documentation .
You can also report bugs in the lcsim bug tracker . Finally you can use the linear collider discussion forums to ask questions about using the org.lcsim package.
