 ## ROOT and interoperability with ROOT
 
 For many particle physics experiments, a lot of data is stored within ROOT files.  This means at very least one must have the ability to read ROOT files.  ROOT also serves as a tool suite designed to solve many computational problems encountered in HEP, which means that one may want to access some of this tool suite.  The following packages below are worth knowing for these situations:
 
 | Package name | Use | Pro | Con | Further information |
 | ------------ | --- | --- | --- | ------------------- |
+| [ostap](https://github.com/OstapHEP/ostap) | User-friendly & more intuitive interface to(Py)ROOT | Many decorations to ROOT classes | Requires C++ code compilation |  |
 | [uproot](https://github.com/scikit-hep/uproot) | Native Python ROOT I/O | Easy to install, fast, no dependence on C++ ROOT | Although can read all ROOT files, can only write ROOT files with specific objects. | |
 | root_numpy, root_pandas | ROOT to/from Numpy and Pandas, like uproot | full ROOT functionality, like TFormula | slower than uproot, binary incompatibilities with different versions of ROOT | |
 | [ROOT conda](https://nlesc.gitbooks.io/cern-root-conda-recipes/content/installing_root_via_anaconda.html) | Using ROOT within Anaconda | Easy to get ROOT installed with PyROOT support | Not all features of ROOT and getting dated (6.04 Py2.7/3.4 since XENON1T uses that) | [Recipes](https://github.com/NLeSC/root-conda-recipes) |

 ## Speeding up code

 Stealing code from other physicists is its own sign of flattery.  Codes that are abandoned more than two years will get struck through.:
