+[[:|<< back to HepSim manual]]
+====== 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
+</code>
