Dear Hande, Thanks for helping me. It really works and really solves my problem. Just one thing to ask is that, while plotting the bands structure, it generates file.xmgr file. The x-axis are the k-points. But my question is the k-points are three no. (e.g. like 0.5 0.5 0.5), but it convert it in a single number. Can you please tell me the formula, with which it convert? Its a very basic question. And sorry for asking that. regards
