Hi Luca,

I had similar issue with refinement against a low resolution data. However, choosing input model as reference model for restraints (with little bit of playing around with weight factor) took care of this.

I have noticed that real-space refinement in cryoEM maps has a tendency to pull long disordered side chains (Lys, Glu etc) back towards main chain density, resulting in unrealistic hairpin-like bent conformations. Is there a way to counter or moderate this behaviour? It would save me from having to manually straighten them all out again afterwards...

Best wishes,
Luca
