Like a > black hole gobbling up nearby planets (snip)” > Do you have a reference to support this assertion The methodology of the "dirty but very fast" real space refinement in Phenix is described in detail in the article : Afonine, P.V.et al. (2018) "Real-space refinement in PHENIX for cryo-EM and crystallography". Acta Cryst ., D 74 , 531-544. The articel contains also arguments for such kind of procedure, its advantages (the principal goal and advantage is a very high speed) and obvious limitations (one of them mentioned by James). > Hopefully someone from the Phenix team will give some clarifications.
