DiSPy

DiSPy is a utility for applying the distortion symmetry method (DSM) to the calculation of minimum energy pathways using the nudged elastic band (NEB) algorithm. For information on how to run DiSPy, including all relevant and necessary input parameters, see the PDF manual in the "docs" folder. Details on the DSM can be found in Ref. [1-3]. Example calculations can be found in the "examples" folder.

Prerequisites and Compilation

DiSPy is able to run with Python2 or Python3 and requires numpy, spglib and the atomic simulation environment (ASE). It can be manully installed by typing:

python setup.py install

Note that a fortran compiler is required. Testing has been done with gfortran only.
