Thanks for your response, but I've read the manual. What I realized is that, for example, I should consider for every two, three or … atoms, a virtual atom. Here are some questions: 1 - Does not important consider which atoms together? or How much is the angle between atoms? 2 -Does I need to manually sort atoms and consider for every group a virtual site? thanks ramezani
