A web server to calculate the Diffraction Precision Index (DPI)

In the case of anisotropic protein model refinement undertaken at a diffraction resolution worse than  ~1.6 Å the DPI value becomes unstable...    Read more 
The case of PDB files including hydrogens at calculated positions approximately doubles the number of atoms and thereby affects the DPI value...  Read more
