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.

Thanks.
