Deer all, I am trying to use the steered molecular dynamic method to study a triple helix. According to a paper, it can be done through fixing the COM of the three terminal by means of a strong harmonic restrain with a super large spring constant, and pull the C-terminal by an appropriate spring constant in Gromos96 53a6. But I still do not know how to keep the COM fixed. Could anybody give me same guidance?
