Hello
I'm using VASP software for geometry optimization and PXRD simulation pattern generation. I upload a structure of the molecule as xyz. file. When ever I apply the?create a periodic copy?and set the cell parameters for hexagonal Bravais lattice by utilizing the parameters to x=y=20 A, z= 6 A and alpha=beta=90 degree and gamma=120 degree, then the symmetry of the structure changes to?P1 symmetry (default symmetry). And I'm not able to change the symmetry (P6/mmm) or some other. Please, suggest me how can I change the symmetry.

Thanking you

Dear admin
Actually, I have to generate PXRD pattern for organic large molecule which is not possible to draw in VASP. which required to import file and finally, I am not able to change the symmetry. Can you suggest me how can I resolve my problem.
