CCP-EM, CCPBioSim & University of Leeds are hosting two workshops on the theme of combining biomolecular EM and MD techniques.
Structural characterisation of proteins and protein complexes with by cryo-EM and cryo-ET is now providing access to a wide range of macromolecular assemblies that were inaccessible by X-ray crystallography or NMR. Although EM analysis can provide information on different conformational states, it is still an averaging technique and therefore highly dynamic regions can be difficult to resolve. However, the image processing and interpretation of data from these experiments requires sophisticated computational hardware and software. This workshop will explore the emerging computational techniques for achieving biological understanding from cryo-EM/ET images, and discuss areas most in need of further development.

Cryo EM or X-ray? Challenges, Achievements, and Prospects
A hands-on workshop on the new software tool Fluctuating Finite Element Analysis (FFEA), which calculates dynamic trajectories for flexible biomolecules directly from cryo-EM/ET density maps. FFEA aims to provide an equivalent simulation tool for the EMDB as atomistic MD simulations have for the PDB. This approach uniquely, so uses volumetric meshes rather than atomistic co-ordinates as input such that it can model protein dynamics, protein-protein interactions, conformational switching between known configurational states and can be mapped back to atomistic co-ordinates, where these are available. This workshop is ideal for biomolecular simulators who would like to make full use of cryo-EM data in their modelling, or for experimentalists who would like to gain new theoretical insight into the dynamic behaviour of the structures they observe.FFEA tutors: Sarah Harris, Albert Solernou, Daniel Read & Oliver Harlen (University of Leeds)
