        Hi, I have tried to only refine the sidechains in my model using the simulated annealing with commands strategy=individual_sites sites.individual = "sidechain" However after the refinement the backbone was also moved; any suggestions as how to only allow sidechain movements during the refinement? Thanks, Esmael
