The simulations identify an optimal thickness of the water layer at which the efective resolution for imaging the hydrated sample becomes signifcantly higher than for the non-hydrated sample. This efect is lost when the water layer becomes too thick. Even though the detailed results presented pertain to the specifc sample studied, the trends which we identify should also hold in a general case. We expect these fndings will guide future single-particle imaging experiments using hydrated proteins.
