Here is the paper where I hope these questions are answered: Acta Cryst. (1995). A51, 880-887 Also, the implementation of ML target calculation and other relevant calculations in phenix.refine are done exactly as described in this paper. Namely, the ML target in phenix.refine is the formula 14 in the above paper; and the estimation of distribution parameters alpha&beta is described in Appendix phenix.refine is smart about generating the good free-R flags, where all necessary considerations are taken into account. Twinning, if present, is taken care of too. Pavel. On 8/20/2008 12:12 PM, Pascal EGEA wrote:
Hi All,
Following Pavel's answer to Francis Reyes, I have a very basic question about this too.
What is a good distribution of reflections and what are thin bins of resolution to ensure correct ML estimations? Are there any basic statistical rules that should be considered.
Thanks
Pascal
