A worldwide e-Infrastructure for NMR and structural biology

SAXS Services

The SAXS web portals provide access to services and software packages for SAXS that have been ported by the WeNMR consortium to the GRID. 

Ab Initio Shape Determination

    Shape determination by simulated annealing using a single phase dummy atom model

    Rapid shape determination by simulated annealing using a single phase dummy atom model

    Reconstruction of a protein structure by a chain-like ensemble of dummy residues

    Shape determination by simulated annealing using a multiphase dummy atom model


    Evaluation of theoretical solution scattering from known atomic structures and fitting to experimental SAXS data

    Rigid body modelling of complexes with multiple subunits

  • EOM
    Ensemble Optimization Method for unfolded proteins
