Mogul Geometry Check can help identify inconsistencies within a crystal structure and can suggest values to be used for restraints during refinement. 

In this workshop you will explore how to use Mogul to assess the geometry of a molecule using the information in over 1.1 million structures in the CSD.


Learning Outcomes

  • How to run a geometry check in Mercury.

  • How to launch Mogul from Mercury.

  • How to interpret the results obtained.

  • How to restrict the geometry check to a specific feature of a molecule loaded.



  • Mercury installed and a current valid CSD licence active (CSD-Materials or CSD-Enterprise). For installation and licences visit the FAQs.


  • Feeling comfortable with basics of Mercury visualisation:
    • Navigating the Mercury interface.
    • Editing styles and colours.
    • Displaying packing diagrams.
