The following commands should then be executed in order from this working directory to make the slicPandora binary. You should execute each new package build from your working dir.

svn co http://svnsrv.desy.de/public/ilctools/ilcutil/trunk ilcutil
cd ilcutil
cmake .

If this step completes successfully without compilation or link errors, you should see a binary at slicPandora/bin/PandoraFrontend. You are basically done building slicPandora.
Pandora Settings (optional)

cvs -d :pserver:anonymous@cvs.freehep.org:/cvs/lcd co LCDetectors |
For example, see LCDetectors/detectors/sidloi3/sidloi3_pandora.xml and its compact detector description.
PandoraFrontend
The PandoraFrontend binary provides a simple frontend to slicPandora.

This table explains the function of each of these arguments.
order | argument |
|---|---|
1 | geometry xml Geometry XML file |
2 | Pandora settings xml XML file |
3 | LCIO input events |
4 | LCIO output file with PFOs appended |
5 | number of events to run (optional) |
6 | number of events to skip (optional) |
The geometry file is in an XML format. It can be created from a compact detector description using GeomConverter with the option "-o pandora". You are required to provide some additional parameters related to sampling fractions (see LCDetectors/detectors/sidloi3 for example).
The Pandora settings XML file contains settings to configure the Pandora PFA algorithm. Example configuration files can be found in the Pandora Settings SVN project (see building instructions above) (see SettingsPandoraSettings/PandoraSettingsBasic.xml).
The LCIO input events should contain collections of LCIO CalorimeterHits and named according to their subdetectors, plus a collection of LCIO Track objects called "Tracks." There also needs to be a collection called "TrackStates" containing momentum measurements at various points along the Track (see below for details of generating these files).
The LCIO output file will contain the contents of the input file plus the PFO collections created by Pandora, as well as some intermediate collections of hit objects. This file is generated by slicPandora.
Using GeomConverter to Output the Pandora Geometry Format
...
This will create the file sidloi3_pandora.xml that can be used as input to slicPandora.
FIXME: Need to document the conditions used to set sampling fractions.
