Dear gmx-users,

I am working with a system composed by
20 molecules which are aggregated in water. I want to calculate the
dimensions of this aggregate, but it has an elipsoidal shape, instead
of a globular shape, as follows in this representation: 

-----( ____________)------X

Which gromacs tool could I use to
perform this analysis and calculate X and Y (nm) as a function of

I tried using g_gyrate and observing
the Rx, Ry and Rz components, but I couldn't get it right.

Thanks in advance,

Conrado Pedebos.
