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 structure at 2.75Å has a mean
B-factor of 40; however, after adding the ANISOU records as required by
the PDB, I noticed the average B-factors double.
Is this normal?
Sincerely,
Omid
