Hi Hasan,
it sounds like you set up the refinement parameters such that you do
not refine B-factors at all. This is the only explanation I can come
up.
Can you send some more details about the refinement you did:
- did you use command line or GUI
- send a parameter file
etc...

Hi,
I am trying to refine a structure with a bound ligand "PAR".
Unfortunately, input b-factor of the ligand and output values are
matching exactly even tough I copied the ligand from a different
structure.
I manually changed the occupancy of the ligand to see if it
changes the b-factor but again B-factor didn't change.
Can someone help me to solve this issue?
Below, I attached the first four lines of the pdb after occupancy
change.
