DireX - Low-resolution Structure Refinement

DireX performs efficient geometry-based conformational sampling of protein structures under experimental restraints. It combines prior structural information with experimental data through the Deformable Elastic Network (DEN) approach which drastically reduces over-fitting.

Experimental restraints which can be used in the current version are:

To get a first impression: Watch a movie of fitting Elongation factor 2 (EF-2) into an 8 Å density map.
