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

Yes, as Dale says when the FreeR goes up after minor rebuilding you have
usually somehow picked up a different FreeR set..
This is almost certainly what causes this to happen - you say

Are you sure you have identified the correct space group?

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
