The problem :

How to interpret low-resolution reconstructions of macromolecular assemblies (typically Transmission EM reconstructions) at atomic scale ?

The problem can be solved in the particular but frequent case where subunits are known at atomic scale (typically MX or NMR molecular models).

Our solution :
The main idea is to fit the available atomic models (considered as rigid bodies) into the EM reconstruction.

The method is to compare, the EM map with a calculated model-based electron density within a selected volume.

The numerical problem consists in determining and optimizing the variables that specify the positions of the rigid models within the macromolecular assembly.

What is VEDA ?
VEDA is a visual environment developed to fit interactively atomic models into 3D reconstructions. Calculations are performed in reciprocal-space and the symmetry of the reconstruction is taken into account. The computations are fast and an entire EM reconstruction can be used.
