> All.
> I have been trying to implement residual dipolar coupling restraints into my AMBER 7 molecular dynamics calculations but I am not happy with the resulting distance (55.8) and alignment penalties (216.47). I think I may be implementing the rdcs incorrectly as I have been successful using them in X-PLOR and had very small restraint violations.
> My input file and rdc restraint file are shown below.
