RooUnfold

Fork from http://hepunx.rl.ac.uk/~adye/software/unfold/RooUnfold.html

RooUnfold is a framework for unfolding (AKA "deconvolution" or "unsmearing"). It currently implements several methods: iterative (Bayes), singular value decomposition (SVD), unregularised matrix inversion, bin-by-bin (simple correction factors), and an interface to ROOT's TUnfold. It can be used from the ROOT prompt, or linked against the ROOT libraries. RooUnfold requires ROOT 4 or later.

For the latest version and documentation, see here

http://hepunx.rl.ac.uk/~adye/software/unfold/RooUnfold.html

RooUnfold was written by Tim Adye, Kerstin Tackmann, and Fergus Wilson.

Building

Since version 2 RooUnfold is using cmake to find dependencies and create the MakeFile:

cmake CMakeLists.txt
make jobs=2

to build the RooUnfold shared library.

Tests

In order to run the boost tests for RooUnfold simply

make test

If you want to run specific tests you can do this with

# a single test suite
./RooUnfold_test --log_level=message --run_test=TestRooUnfoldSvd
# a single test case
./RooUnfold_test --log_level=message --run_test=TestRooUnfoldSvd/test_get_tau_from_constructor

Running

RooUnfoldExample.cxx makes a simple test of RooUnfold.

% root root [0] .L examples/RooUnfoldExample.cxx root [1] gSystem->Load("libRooUnfold.so"); root [2] RooUnfoldExample()
