2014-11-20 Thread Edward A. Berry
Using a percentage might be justified as a trade-off between having ample free reflections for statistics and cutting too deeply into your completeness of working reflections for refinement. It seems to be generally agreed that 2000 free reflections is sufficient to guide your choice of refine

-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 I think is is just a matter of convenience when changing resolution limits and trying to use the same test set. If you always want 1000 but your next crystal doesn't diffract as well you have to select a few more reflections and they will have bee

[ccp4bb] Free Reflections as Percent and not a Number

2014-11-20 Thread Keller, Jacob
Dear Crystallographers, I thought that for reliable values for Rfree, one needs only to satisfy counting statistics, and therefore using at most a couple thousand reflections should always be sufficient. Almost always, however, some seemingly-arbitrary percentage of reflections is used, say 5%.
