 Input data can be prepared using the graphical user interface PWGui, by Anton Kokalj
 An alternative graphical user interface (also for WIndows and Mac): BURAI by Satomichi Nishihara (Version 1.3 available here)
 Visualization of the results can be obtained using XCrySDen
 Other visualization software that can produce input data or read output data for Quantum ESPRESSO:
 GDIS
 JICE (online converter available at this link)
 VMD
 VESTA.
