Hi All. I think I have asked this before but forgot. Old age. What is the appropriate number / percentage of reflections to flag for a statistically appropriate Free-R calculation? If I am correct, the reflection file editor in Phenix chooses by default either 10% of the measured reflections or 2000 whichever comes first.
