[RASMB] ellipsoids of revolution

[John Philo]

Mitra,

Basically this is done by calculating the absolute size of the ellipsoid
with the given axial ratio that gives the same total volume as the anhydrous
volume of that molecule. Then traditionally the hydration is added as a
uniform expansion of the whole ellipsoid to give the correct total volume.
All of this has been implemented in SEDNTERP, which will plot the shape and
size, and the details of how the anhydrous volume is determined are
described in the Help file.

Hi all

I have a very basic question. How does one get from determining the a/b
ratio to the gross molecular dimensions of the protein molecule. The
molecular weight should place a limit but I am a bit fuzzy as to how exactly
this is carried out.
