SANDECALClustering takes as input the digitized photodetector signals in <digit file> and produces clusters of reconstructed cells in the ECAL. The output <cluster file> has the following structure:
cluster
cluster.tid
cluster.x (y, z)
cluster.t
cluster.e
cluster.ax (ay, az) #apex
cluster.sx (sy, sz) #direction
cluster.varx (vay, varz) #variance
cluster.reco_cells
Each reco_cell object has the following structure:
int id;
double z;
double y;
double x;
double l;
int mod;
int lay;
double e;
double t;
dg_ps ps1; #photodetector 1 digitized photo-signal
dg_ps ps2; #photodetector 2 digitized photo-signal
Currently, there are only two supported building and development environments:
FNAL machines are Almalinux9 and the supported package manager is Spack. Documentation can be found here.
To build and install sandreco using spack, download the installation file and run it.
curl -O https://raw.githubusercontent.com/wiki/DUNE/sandreco/files/install-sandreco-with-spack.sh
source install-sandreco-with-spack.sh <spack installation folder>When the script ends to run, you are ready to use sandreco.
To develop sandreco, first install edepsim downloading the installation file and run it.
curl -O https://raw.githubusercontent.com/wiki/DUNE/sandreco/files/install-edepsim-with-spack.sh
source install-edepsim-with-spack.sh <spack installation folder>Then, build sandreco using the following commands:
mkdir <installation path>
cd <installation path>
git clone https://github.com/DUNE/sandreco.git
cd build & mkdir build
spack load [email protected]
spack load [email protected]
spack load [email protected]

make installOn the CNAF machine run, CMake is used to build sandreco using the following commands:
mkdir <installation path>
cd <installation path>
git clone https://github.com/DUNE/sandreco.git
sed -i "s:set(CMAKE_CXX_STANDARD 17):set(CMAKE_CXX_STANDARD 14):g" sandreco/CMakeLists.txt

The sandreco project provides six executables:
- Digitize will perform digitization,
- SANDECALClustering will clusterize the ECAL DAQ digit in clusters of reconstructed cells,
- Reconstruct will reconstruct tracks in STT and clusters in ECAL
- Analyze will identify particles and assign them a momentum
- FastCheck will produce a lot of plots to check everything is ok
- Display displays events
The executables exploit two libraries:
- libUtils.so for utilities
- libStruct.so for i/o
- Create digits of STT and cells of calorimeter
$ Digitize <MC file> <digit file>- Create clusters of ECAL reconstructed cells (output
<cluster file>is not an input argument)
$ SANDECALClustering -d <digit file>- Track find and fit of STT track
- Clustering of calorimeter cells
$ Reconstruct <MC file> <digiti file> <reco file>- Evaluate parameters of particles
- Evaluate neutrino energy
$ Analyze <MC file> <reco file>- Produce several plots to check everything is ok
$ FastCheck <root file> <pdf file>- Display an event
$ Display <event number> <MC file> <input file> [show trajectories] [show fits] [show digits]The description of the data format can be found here
- The code format can be find here
- The developing scheme is described HowToDevelop.pdf
