Before revision:  On the interface level the entropy of the small interface assembly system is approximated by the sampling of the configurational space using the recently reported geometric method called  EASAL (efficient atlasing and sampling of assembly landscapes) .
After revision:  On the interface level the entropy of the small interface assembly system is approximated by the sampling of the configurational space using the recently reported geometric method called of selected subassembly landscapes for each interface type and their abbreviated EASAL (efficient atlasing and sampling of assembly landscapes) .
