cif2x

In recent years, the use of machine learning for predicting material properties and designing substances (known as materials informatics) has gained considerable attention. The accuracy of machine learning depends heavily on the preparation of appropriate training data. Therefore, the development of tools and environments for the rapid generation of training data is expected to contribute significantly to the advancement of research in materials informatics.

Cif2x is a tool to generate input files for first-principles calculation software. It takes crystal structure data in CIF format and input parameters as a template, and constructs the parts that vary depending on the type of material and conditions. It is capable of generating multiple input files tailored to specific computational conditions. Currently, it supports VASP, Quantum ESPRESSO, OpenMX, and AkaiKKR.

getcif is a tool to retrieve crystallographic information and other properties of materials from databases. The latest version of getcif provides access to Materials Project database. Users can search database and obtain information by specifying symmetry, composition, or physical properties of materials.

Target applications

Quantum ESPRESSO, VASP, OpenMX, and AkaiKKR.

Requirement

Python3 with pymatgen, qe-tools, AkaiKKRPythonUtil, and other library packages.

getcif requires mp-api, pymatgen, and other library packages.

Install

  • From source
python3 -m pip install DIRECTORY_OF_THE_REPOSITORY
