* `SeeK-path <https://www.materialscloud.org/work/tools/seekpath>`_: A k-path finder and visualizer
* `Bilbao Crystallographic Server <https://www.cryst.ehu.es/>`_
* Pseudopotential libaries for Quantum Espresso

 * `GBRV high-throughput pseudopotentials <http://www.physics.rutgers.edu/gbrv/>`_

   This is ultra-soft PSP lib. It provides for all elements within PBE functional except noble gas, radioactive and rare-earth groups. Energy cutoff was not tested.

 * `PseudoDojo <http://www.pseudo-dojo.org/>`_

   This is Norm-conserving PSP lib generated by `ONCVPSP code <http://www.mat-simresearch.com/>`_. It provides for all elements with LDA, PBE and PBEsol functionals. Energy cutoff was tested. There are both scalar- and full-relativistic versions.

 * `SG15 ONCV Potentials <http://www.quantum-simulation.org/potentials/sg15_oncv/index.htm>`_

   This is Norm-conserving PSP lib generated by `ONCVPSP code <http://www.mat-simresearch.com/>`_. It provides for all elements within PBE functional except radioactive and rare-earth groups. There are both scalar- and full-relativistic versions.

 * `Rare Earth PAW datasets <http://www.mineralscloud.com/resources/repaw/index.shtml>`_

   This is PAW lib. It provides only for rare-earth group from La to Lu.

 * Standard solid-state pseudopotentials (SSSP): `SSSP precision <https://www.materialscloud.org/discover/sssp/table/precision>`_ and `SSSP efficiency  <https://www.materialscloud.org/discover/sssp/table/efficiency>`_

   This is a combined PSP lib. It selected the best PSP for each element from different libraries such as GBRV, SG15, Pseudo Dojo, pslibrary, Goedecker, THEOS and RE Wentzconvitch. All elements are provided within PBE functional but the PSP-type can be ultra-soft, norm-conserving or PAW. Energy cutoff was tested.
