[phenixbb] Can I limit the model's B factor range during refinement

Dear all, Several models have been refined using Phenix recently. It works well . But the model's B factors in some region are very high, higher than 150 or more. Of course, the wilson B is high too, about 60-70. I remembered that the B factor can be limited in the refinement using Refmac. Can I do the similar thing in Phenix ? Thanks in advance! Best wishes, leo
