MPmorph is a collection of tools to run and analyze ab-initio molecular dynamics (AIMD) calculations run with VASP, and is currently under development. It relies heavily on tools developed by the Materials Project (pymatgen, custodian, fireworks) and atomate.

MPmorph provides:

• Infrastructure for dynamic VASP MD workflows:
  • Tools to create dynamic MD workflows using atomate
  • E.g. generation of new MD runs based on the given criterion (currently pressure, for liquid/amorphous phase density estimation)
• Tools for statistical analysis of:
  • Static observables:
    • Radial distribution functions
    • Coordination numbers
    • Voronoi analysis
    • Polyhedra connectivities
    • Thermodynamic quantities
  • Diffusion coefficients:
    • Robust calculation of diffusion coefficients (D) and activation energies (Q).
    • Rigorous error analysis for D and Q.
