Description
We present a suite of software for every part of the workflow for evaluating correlation functions on an ensemble of gauge configurations: the construction of irreducible hadron operators, the enumeration of Wick contractions, and the resultant tensor contractions. The workflow is illustrated for correlators between one-, two- and three-hadron operators present in the excited nucleon spectrum using a small-volume CLS lattice at $m_{\pi}=280\,{\rm MeV}$.
