What is this?

This repository contains code (originally by Callum) and input GDMLs for building the merged 2x2 + MINERvA geometry.

What do I need?

You need the pyg4ometry package, which can be installed via pip. Be warned, the installation will use every core on your machine to compile the necessary C++ libraries.

What do I do?

Run, for example, pyg4_mod_and_add_newMINERvA.py.
