ROOT
ROOT is an
object-oriented program and library developed by CERN, aimed at solving
the data analysis challenges of high-energy physics.
It was originally designed for particle physics data analysis
and contains several features specific to this field, but it is also
used in other applications such as astronomy and data mining.
ROOT is currently mainly used in data analysis and data
acquisition in high energy physics experiments — most current
experimental plots and results are obtained using ROOT.
Features include:
- Provides packages for:
- Histogramming and graphing to visualize and analyze
distributions and functions
- Curve fitting (regression analysis) and minimization of
functionals
- Statistics tools used for data analysis
- Matrix algebra
- Four-vector computations, as used in high energy physics
- Standard mathematical functions
- Multivariate data analysis, e.g. using neural networks
- Image manipulation, used e.g. to analyze astronomical
pictures
- Access to distributed data (in the context of the Grid)
- Distributed computing, to parallelize data analyses
- Persistence and serialization of objects, which can cope
with changes in class definitions of persistent data
- Access to databases
- 3D visualizations (geometry)
- Creating files in various graphics formats, like
PostScript, JPEG, SVG
- Interfacing Python
and Ruby code in both directions
- Interfacing Monte Carlo event generators.
