NCS axis is not parallel to any crystallographic axis. Although initially had some problem in refinement because of twinning. I did not have any problem in obtaining the solution. So my doubt was that even though there was an indication of pseudotranslation, why was there no problem in obtaining the solution? So I wanted to know whether this pseudotranslation peak was due to the presence of heavy atoms in the structure. > > > Tommi Kajander, Ph.D., Docent > Macromolecular X-ray Crystallography > Research Program in Structural Biology and Biophysics > Institute of Biotechnology > P.O.
