Nowadays nanotechnology allows one to observe single proteins at work. Under atomic force microscopy (AFM), e.g., their surface can be rapidly scanned, and functional motions monitored, which is of great importance for applications in all fields of the life sciences. The analysis and interpretation of experimental results remains however challenging because the resolution of obtained images or molecular movies is far from perfect. On the other side, high-resolution static structures of most proteins are known, and their conformational dynamics can be computed in molecular simulations. This enormous amount of available data offers a great opportunity to better understand the outcome of resolution-limited scanning experiments.
