The STARANISO Server
Anisotropy of the Diffraction Limit
If you have some results that illustrate some beneficial effect of using the server on your data, and that you are happy to share with the community, please email the contact address at the bottom of the page.
This development is in line with our philosophy of making as few prior assumptions as possible about the data (motto: "Let the data speak!").
Implicit assumptions made (incorrectly) by some software - namely that the anisotropic diffraction-limit surface is ellipsoidal with principal axes either parallel to the crystal axes or to the principal axes of the anisotropy tensor ellipsoid - were already relaxed in the previous version of the server, through a complete separation of the rôles of the anisotropic diffraction limit and of the anisotropy tensor.
With this new development of a protocol for anisotropy correction at the unmerged data stage, we go further.  By applying the anisotropic diffraction cut-off at an earlier stage in processing to the unmerged data, we try to ensure that weak measurements that can impact the quality of the final data by biasing the image scales and the error model can be eliminated early on in the process.
You are strongly advised to disable any Java plug-ins that were installed solely for the purpose of using previous versions of this server but are now no longer needed.
