In our paper we state that the strcuture proposed by Robinson et al. in their paper * , the "one start interdigitated structure", is similar to our fiber structure for 177bp repeat length, the"five start structure".
To give our readers a better idea to our of their similarity we made a movie of the transition between those two structures. The movie is available here :

The topology of the fiber is the same in both configurations but the nucleosome tilt is slightly different.
