Spinach is a fast spin dynamics simulation library that supports NMR, EPR, DNP, MAS, Optimal Control, PHIP, singlet state NMR and other forms of Magnetic Resonance spectroscopy.

Simulating large spin systems require intense computational power. Spinach reduces this requirement by dropping from the simulations a large number of states in systems which never contribute to the system trajectory. As a reference, liquid-state NMR experiments with 40+ spin systems can be simulated on a workstation.

The minimum supported version of Matlab is 2016b (64-bit version) with Parallel Computing Toolbox, Optimisation Toolbox and at least 8 GB of RAM. Spinach supports NVidia Tesla GPUs and large-scale (128+ cores) parallel deployments using Matlab Distributed Computing Server.

Spinach can be used with a Graphical User Interface (GUI) called Spinach GUI, which also introduces a simple and general XML format for spin system description. The same GUI can be used with Simpson and EasySpin simulation packages. Although Spinach can be used with any operative system that supports Matlab, the GUI is only available for Windows operative systems.
