 ## SMATool Stress Calculators
-SMATool utilizes VASP (Vienna Ab initio Simulation Package) and QE (Quantum Espresso) as its calculator, ensuring high accuracy and reliability. These powerful electronic structure codes, combined with the ASE (Atomic Simulation Environment) backend, enable detailed and precise material analysis. If you're interested in other electronic structure code as the stress calculation, we will be more than happy to collaborate in such implementations.

 ## SMATool Utility
 ASP electronic structure calculations come with proprietary pseudopotentials included in the package. In contrast, Quantum Espresso (QE) is open source, offering a variety of sources for obtaining pseudopotentials. While no specific pseudopotential database is officially recommended for QE, we prefer the norm-conserving [Pdojo pseudopentials](http://www.pseudo-dojo.org/). The SMATool computational toolkit includes an automated utility package, `qepotential`, located in the utility folder. This tool automates the generation of pseudopotentials from the Pdojo website for all materials required to run the SMATool package with QE as the calculator. Users can also specify custom requirements in the `pseudo.info` input file. The SMATool utility package saves the potentials of various elements as `element_pdojo.upf` in the `qe_potentials` folder.
