Hello Xiang,<br>
<br>
short answer: try refining with all defaults plus weight
optimization. If that does not go well please send me data and model
files and I will do my best to make it work.<br>
<br>
Longer answer: the way B-factor restraints are implemented in
phenix.refine (that you can learn about in corresponding paper)
allows refining individual Bs at any resolution. So this is why this
is the first choice to try. If that does not work it's best to a)
let us know and b) try group B refinement.<br>

</div>
<div>I am working on my ~6A data with molecular replacement
method. The MR works out and after rigid body and xyz
refinement the result is OK. However, when I tried the ADP
refinement with Group B factor option in PHENIX GUI, the R
factor significantly increased as well as the B-factor. Any
expert can help me to take a look and give some suggestions
please?</div>

<div>Thank you very much for your help!</div>
