[Pw_forum] Atomic position for Vc-relax

[Ridwan Agbaoye]

I did vc-relax calculations for silicon and at the end of the calculation i got my final lattice parameter and atomic positions, but to my surprise when i viewed my new structure with my new atomic positions, it does not look like a face centered crystal structure but preparing the input file with the old atomic position its look perfecting like the face centered crystal structure with atom on all of the faces 
Does this mean that the new atomic positions should not be used for calculation after vc-relax because the old atomic position looks better when viewed with xcrysden
