Dear all, I am currently refining a structure using PHENIX 1.5-3 and have encountered some problems with "exploding residues". I have attached a image (small PNG file) highlighting the problem. Has anyone had a similar experience? Or know the solution to the problem? Change weighting in favour of geometry ? Many thanks, Tony Oliver .
