uproot3-methods

Pythonic mix-ins for ROOT classes.

This package is typically used as a dependency for uproot 3.x, to define methods on the classes that are automatically generated from ROOT files. This includes histograms (TH*) and physics objects like TLorentzVectors. The reason it's a separate library is so that we can add physics-specific functionality on a shorter timescale than we can update Uproot 3 itself, which is purely an I/O package.

Occasionally, this library is used without Uproot 3, as a way to make arrays of TLorentzVectors.

Note: this package is incompatible with awkward>=1.0 and uproot>=4.0! For Lorentz vectors, use vector. Since the versions of Awkward Array and Uproot that this is compatible with are deprecated, this library is deprecated as well.

Installation

Install uproot3-methods like any other Python package:

pip install uproot3-methods               # maybe with sudo or --user, or in virtualenv

Dependencies:
