The FINDSYM code (http://stokes.byu.edu/iso/findsym.php) takes as input a primitive or conventional cell and returns the primitive cell along with the Wyckoff positions, space group and primitive lattice vectors/constants. Cheers, Vahid Vahid Askarpour Department of Physics and Atmospheric Sci

if you know the Wyckoff position you can estimate it. On Dec 25, 2017 1:56 PM, "Madhurya Chandel" wrote: > Thank you so much for your reply. > > In input script you have given conventional unit cell, and all calculation >> in pwscf are done via primitive unit cell. >> > How i can get to know t

In input script you have given conventional unit cell, and all calculation in pwscf are done via primitive unit cell. So in output script it is primitive unit cell. No need to worry, just take optimised coordinate from out put... On 25-Dec-2017 6:05 PM, "Madhurya Chandel" wrote: Dear QE users

Dear QE users I have a small doubt that after optimization (relax) does the number of atoms change? Because in my case its happening. For the reference, I am attaching the input and output images of the unit cell. Please have a look. With regards *Madhurya Chandel* *Research Scholar * *Dep
