It's similar ONLY in the sense that the data are modelled with a linear
combination of basis functions using nonnegative constraints for
the amplitudes. In C(s) the model is a sum of Lamm equations, in the
equilibrium case its a sum of exponentials. In C(s) you get a distribution
of S-values, in this particular model of UltraScan's equilibrium function
you get a distribution of molecular weights which describe the modelled
data. Just as you have to input a range of S-values for C(s), you will
have to supply a range of MW's and specify the number of basis functions
to limit the search. 

Other predefined and user-defined models in the software can be used to 
fit self-associating and hetero associating systems.

More detailed info can be found in the online documentation.
