In the past, I used as a default, 5% of my unique reflections for the Free R test set. I have a high resolution structure with 150,000 unique reflections and noticed that Phenix defaults are 5% or 2000 reflections which ever is smaller. What is the current consensus on an adequate number of unique reflections to use for cross-validation?</div><div><br></div><div>Thanks!</div><div>Joe</div><div><br></div><div>P.S. I really, really love Phenix. <br><div>
