This tutorial will show you how to process SLIC output files with the Pandora PFA New package, currently the best performing PFA algorithm, in order to produce Particle Flow Objects (PFOs) (also called ReconstructedParticles) for analysis. It covers building and installing a slic-specific frontend called slicPandora and all its dependencies. Then it will go through the steps for processing slic output using LCSim in order to prepare it for Pandora. Finally, it shows how to run slicPandora using these events. There is also a note on how to generate Pandora detector XML files from compact descriptions.
Building SlicPandora

Preliminary Setup
A Linux or Unix platform is assumed and the bash shell is used for all command-line instructions. The actual setup procedures have been tested on Redhat Enterprise Linux 5.5 (Tikanga).

Build Instructions
| Warning | ||
|---|---|---|
| ||
Old versions of PandoraPFANew will not work, due to changes and additions to its API. It is recommended to use the last tagged version. The build instructions on this page use tagged versions of PandoraPFANew and PandoraMonitoring. Commands for using the trunk versions instead are listed as comments. |
...
You need to have a preexisting installation of ROOT, which is not covered here.
From a bash shell terminal, the following commands should produce a working version of slicPandora.
