I know i need to build a supercell for my compound but, <br></span></div><div><span>i don't understand how to do it. I went through all the examples files, but none was able to give the information. I will</span></div><div><span>be delighted if you can all come to my aid. for example ZnSe with atomic position of (0,0,0) and (0.25,0.25,0.25). <br></span></div><div><span>How do i build a supercell for this compound? </span></div><div> </div><div>Adetunji Bamidele Ibrahim<br>Department of
