[Chimera-users] Hydrodynamic radius

[Tom Goddard]

Hi Sudheer,

  Chimera isn't able to compute hydrodynamic radius of maps or 
molecules.  Are you primarily interested in diffusion properties or 
optical properties of your structure?  Do you think the hydrodynamic 
radius for a uniform solid bounded by a contour surface of your map 
would be useful?  Do you mean Stokes' radius or the R_H defined on the 
wikipedia page?

    http://en.wikipedia.org/wiki/Hydrodynamic_radius

The latter looks like a pretty simple calculation.

    Tom
