Dear Nika, XDS probably did what you asked it to do ;-) This is, however, not a problem. You only need to refine for a couple of rounds longer to gain independence of your Rfree set. No need to reassign them. Depending on the refinement program, it may take many rounds. With Refmac (or shelxl),

Hello, Two days ago I was asking about R free rising. The problem was xds adds R free flags already and then re-introduced them in Phenix, causing R free to rise. I would like to thank you for your answers, they were most helpful. Best, Nika From: Nika Žibrat Sent: ponedeljek, 02. november

Hello, I am trying to solve an X-ray structure of a protein of which the structure is already known. My aim is to only seek for ligands (soaking) and interpret any conformational changes. Since I am using a model with 100% sequence identity from PDB I am not doing Autobuild after Molecular
