[phenixbb] low res structures and Phenix

Hi, I have a couple of questions regarding low res structures in Phenix (about 3.5 angstroms res). 1. Can Phenix do B-factor sharpening for improved maps? If not what program do people usually use for this? 2. How can one optimize Ksol and Rprobe (bulk solvent model) in Phenix? 3. Are there any other suggestions for dealing with low resolution structures in Phenix? Thanks, John Bruning
