Dear Gao Zhe: Yes, I run it from a terminal by typing : "./gdis", But nothing happened. BTW: How do you prepare the input file? PWgui + xcrysden? is there any builder can modify atom positions and save in pwscf input file? This is what i am looking for. Would you mind sharing your experience with me? This is my first day dealing with QE :).
Thank you very much! Jinghui
