Dear Oleksandr Voznyy:
Thank you very much for your reply at first ,and I want to ask a question again,When I have took account into spin polarize,and I got the RHO and DRHO file ,I can get the spin density distribution from RHO file by XCRYSDEN, I got the picture from DRHO by XCRYSDEN ,whether it is related to spin density or not ? thank you very much for your reply again. sincerely yours zhiyong
