SDA functionality

SDA 7 can be used to carry out Brownian dynamics simulations of the diffusional association in a continuum aqueous solvent of two solute molecules, e.g. proteins, or of a solute molecule to an inorganic surface. SDA 7 can also be used to simulate the diffusion of multiple proteins, in dilute or concentrated solutions, e.g., to study the effects of macromolecular crowding.

For a description of the functionality, see the documentation and references.

Changes compared to previous releases can be found in CHANGES.TXT.

The current version of SDA (Simulation of Diffusional Association) may be downloaded from this page:
