ClusterTools

Tools to evaluate SDHCAL software clustering quality and compute cluster properties.

License

Code licensed under the CeCILL 2.1 license :

Installation

  • mkdir build
  • cd build
  • cmake ..
  • optional : make test
  • make install

Installation with ROOT

If you have ROOT installed, you can replace cmake .. by cmake -D BUILD_WITH_ROOT=ON ..

In that case, if your LD_LIBRARY_PATH points to the lib directory, you can convert the ASCII output of the ClusterTools_exe executable to a ROOT TTree. At the ROOT prompter do

.L ../lib/libClusterTools.so
TTree dummy // to get the TTree shared library loaded
TTree *t=ClusterPairsDataSums_ASCIItoTTree("random_test.txt")

and then, you can do

t->Draw("data.a()")
t->Draw("data.RandIndex()")

Installation with LCIO

If you have LCIO installed, you can replace cmake .. by cmake -D BUILD_WITH_LCIO=ON ..

The installation with LCIO allows to use LCIO files with LCIO::EVENT::CalorimeterHit and LCIO::EVENT::Cluster as input to compute sums to estimate cluster set differences like Rand index.

2 executables are built by the LCIO build option :

ComputeSums_from_LCIO to Compute the sums and ClusterTools_LCIOwrite_test to write a LCIO file that can be used as input to test the behaviour of ComputeSums_from_LCIO

installation with LCIO and ROOT

In this case, the ComputeSums_from_LCIO executable will store the computed sum in ROOT trees.
