[Chimera-users] how to generate different starting points to do md simulations

Dear chimera users, I have a small peptide of 20 residue length and I would like to do the simulations of this peptide at different starting points. How could one can generate the different starting points? Can I use the replica exchange MD simulations to generate the different starting points? I request you to please suggest me how to generate different starting points of peptide. Thanks in advance Surya Graduate student India.
