<DIV>Dear wien users,</DIV>
<DIV> I want to make a 72-atom supercell with 12 unit cells of TiO2 where one Ti atom has been replaced by a Cd atom as a exercise.Based on the U.G. , we should put the impurity into the cell. I do not know how to modify the created supercell-structure file by replacing one atom with an impurity. </DIV>
<DIV> Thank you in advance!</DIV>
<DIV> The created supercell-structure file as followed: </DIV>
