An integrated user-interface program for high-throughput first principles calculation through VASP code
Brief Introduction
VASPMATE is very user-friendly and powerful command line code for VASP pre and post processing to derive various properties of materials. The powerful pre-processing capabilities include various structures modeling and calculation parameters setting, while the post-processing analysis includes the derivation of electronic, energetic and other physical and chemical properties. In addition, VASPMATE provides simple and neat command mode, which can be readily used to build several robust HT workflows with lightweight script. It has also been implemented in SPaMD to facilitate the design of user-friendly graphical interfaces, which helps in customizing the complex workflow for automatic derivation of various properties by means of first-principles computations. The efficiency and functionalities of this program were critically validated by conducting several evaluations and tests, which provided guidance and confidence in its potential applications for targeted first principles calculations. VASPMATE is written in C/C++ that may be compiled and runs under linux, mac and win systems, which is small, portable and easy to operate.
Pre processing
The pre-processing provides the remarkable ability for the supercell construction, the redefinition of equivalent cell, the coordinate system conversion, the modification and fixation of atomic coordinates, the deformation of supercell, the setting for k-points, various necessary parameters, and the potentials.
Post processing
The post-processing focuses mainly on the basic electronic and thermodynamic properties, e.g. Kohn-Sham orbitals, band structure, density of states, charge density difference, Fermi surface, thermo energy correction, cohesive energy, formation enthalpy, elastic properties, SQL database etc.
