Xplor group, Pleaes forgive the nieve question,
I am using xplor to put togther a structure with a very small number of constraints. I would like my helixes to behave as rigid bodies. With dyana, I can simply weight the helix building constratins more strongly than my other NOEs by adding a weighting interger after the contacts in the .upl file. Is there a simple way to do this with Xplor? Thanks! -John
