Hi Joe, this is weird... Could you please send me the model and data files for investigation? Thanks! Pavel. On 8/31/10 3:40 PM, Joseph Noel wrote:

Hi All.

Me again! LOL I am sure this has come up and related to how the "B-factor" in the refined PDB's ADP column is calculated including the overall anisotropic B-factor, etc but is it unusual to have isotropic ADPs refine to 0.00? I have several nice structures with 0.00 isotropic ADPs. I am not refining TLS or anisotropic ADPs at all. Just the normal course of refinement. These are regions of a high degree of order and the maps are beautiful but just wandering what the 0.00 ultimately means particularly when I eventually submit to the Protein Data Bank.

P.S. Nat's tips on COOT and Phenix are working beautifully now! Thanks Nat! ___________________________________________________________ Joseph P.
