Cloning the repository in netbeans

  • select team > Git > Clone...
  • enter the repository url: https://github.com/sly2j/clasrec-ltcc.git, click 'next'
  • select the master branch, click 'next'
  • choose a local directory for the project, click 'Finish'
  • if prompted, click "open project"
  • the project will appear in the side bar

Building the plugin and installation in COATJAVA 4

  • obtain the newest version (>=4) of COATJAVA.
    • When working with COATJAVA in a terminal, ensure that the COATJAVA environment variable is set to the relevant directory.
  • click build to build the plugin
  • copy clasrec-ltcc-1.0-SNAPSHOT.jar from the target directory to $COATJAVA/lib/services
  • copy the cluster bank definitions to etc/bankdefs/hipo/LTCC.json to $COATJAVA/etc/bankdefs/hipo

Testing the plugin

  • ensure the plugin is fully installed
  • (optional) convert evio file to hipo:
  • To run the clustering algorithm, run $COATJAVA/bin/recon-util -i data.hipo -o reco.hipo org.jlab.service.ltcc.LTCCEngine
  • If you want to enable DEBUG output
    • set the LTCCEngine.DEBUG flag to true in netbeans (defined in org.jlab.service.ltcc.LTCCEngine.java)
    • rebuild/re-install

Diagnostic histograms using netbeans

Generating/viewing the histograms

  • in netbeans, open the source file org.jlab.service.ltcc.LTCCViewer
  • on line 100, modify String inputfile = "/path/to/your/reconstructed/file.hipo;" to point to the relevant file
  • select run > Run File
  • the output canvas will appear in a new JFrame

Modifying the histograms

  • The available histograms are defined in org.jlab.service.ltcc/LTCCHitHistos.java and org.jlab.service.ltcc.LTCCClusterHistos.java
    • Each of the histograms are created, some options are set, and then they are added to the LTCCHistogrammer
    • This add call also requires a 'getter', a function (typically a lambda) that takes an object of the type DataType and returns a double (for H1F) or Pair<Double, Double> (for H2F).
    • You can add/modify the histograms here
  • To control which histograms are drawn, modify the LTCCViewer.drawClusters() and LTCCViewer.drawHits() methods in org.jlab.service.ltcc.LTCCViewer.java
