Dear All, I am working on a perfectly twinned data in space group P31. when I refine this data with phenix refine the R/Rfree is 26.6/29.4 and average B-factor is 38.
I did one test now..... I used phenix refined pdb and refine with refmac5 and got R/Rfree of 26.2/29.7 and average B-factor is 64. Now I used refmac5 refined pdb and refined with phenix again. Now R/Rfree is 22.1/24.8 and average B-factor is 56. My question is, why B-factor gone up now and R/Rfree reduced. In which refined model should I believe in. If last refined model is true then how should I reduce the B-factor? Thank you Rajesh -- ---xxxxx---- With regards Rajesh K.
