===== What is the resolution limit to choose ? =====

As recommended by Diederich, keep everything up to CC(1/2) of 0.1 in XDS

A CC* of 0.5 corresponds to CC(1/2) of 0.15


//Paired refinement//: to get the statistics of a modeled refined at "high resolution" to a given "lower resolution" without changing the parameters (for instance R(1.9) at 2.0) use Phenix command line

<code>>phenix.model_vs_data high_resolution=2.0 toto.pdb toto.mtz</code>
