====== Creating full detector simulations ======

To create full simulations, you will need to convert ProMC files  to LCIO files. This is described in
[[community:hepsim:usage_truth#converting_to_lcio]]

====== How to make changes in compact.xml ======

If you want to make changes in the detector design, edit "compact.xml", and then run the converters:
<code bash>
JAVA_OPTS="-Xms2048m -Xmx2048m"
GCONVERTER=lcsim/detector-framework/target/lcsim-detector-framework-3.1.6-SNAPSHOT-bin.jar
GEOM="mydetector" # name of your detector
java $JAVA_OPTS -jar $GCONVERTER -o lcdd compact.xml $GEOM.lcdd
slic -g ${GEOM}.lcdd  -G ${GEOM}.gdml
echo "heprep compact.xml.."
java $JAVA_OPTS -jar $GCONVERTER -o heprep compact.xml $GEOM.heprep
echo "pandora compact.xml.."
java $JAVA_OPTS -jar $GCONVERTER -o pandora compact.xml $GEOM.pandora
java $JAVA_OPTS -jar $GCONVERTER -o html compact.xml ${GEOM}.html
</code>
where "${GEOM}" is the name of the detector geometry.  Next, check that you do not have overlapping volumes. Run ROOT with the commands:

<code cpp>
TGeoManager::Import("mydetector.gdml");
gGeoManager->ViewLeaves(true);
gGeoManager->ls("All");
gGeoManager->CheckOverlaps(0.1); //0.1 tolerance or better!
gGeoManager->PrintOverlaps();
gGeoManager->GetTopVolume()->Draw("ogl");
</code>
If you see that some volumes overlap, come back to "compact.xml" and make corrections.

====== Pandora PFA ======

All information required by Pandora algorithm is stored in the file with the extension ".pandora". This file is created using GeoConvertor, which reads CalorimeterCalibration.properties file.
In particular, it reads:

  * mipEnergy
  * mipSigma
  * mipCut
  * timeCut

The sampling fractions are taken from the detector  directory called "SamplingFractions". 
Here files look as this:

<code>
BeamCal.properties*
EcalBarrel.properties*
EcalEndcap.properties*
HcalBarrel.properties*
HcalEndcap.properties*
LumiCal.properties*
MuonBarrel.properties*
MuonEndcap.properties*
README*
</code>


Look at the file:
<code>
lcsim/detector-framework/src/main/java/org/lcsim/geometry/compact/converter/pandora/Main.java
