Dear Ethan, Thank you for your reply. I will try to review my refinement protocol once more; however, I am still perplexed at what lies at the heart of the problem. Overestimation of average B-factor using TLS is perfectly sound, but I am not sure why all my structures the average increases trem

Dear all, I was about to deposit a few structures to the pdb when I noticed the mean B-factors were larger than one might expect. All the structures were refined using TLS refinement. During refinement in Refmac the average temperature factors for each structure is reasonable. For example, a str
