AquaSAXS, a web-based software to calculate SAXS spectra from PDB coordinates, including the solvent density predicted by AquaSol, is now available on-line. See article.
The corresponding software Aquasol to calculate solvation maps is also on line (see article). AquaSol replaces the old PDB_Hydro web server.


A meeting in I. Pasteur of the France-Stanford Exchange Program (September)


MinActionPath (MAP server) was updated (NewPath) to accept up to 10,000 atoms thanks to inew code by Patrice Koehl (UC Davis, USA).


The dipolar solvent model was described in Biophysical Journal (coll. H. Orland).
The web server and new implementation due to P. Koehl (AquaSol) is here.


MinActionPath (MAP) web server: Generate the most probable trajectory between two known structural forms of the same macromolecule (Franklin et al., 2007).


Installation of NOMAD_Ref and PDB_Hydro web servers (see Ref. here and here).
These sites provide online servers for algorithms such as normal mode calculation, structural refinement, solvation, mutation and (later) transition path calculation.
The primary application is for biological macromolecules like proteins or DNA or complexes thereof.

Go to Main site for more details on the group activities.
