Figure : Merged free energy profile from distance and contact space REUS calculation. In this merged representation, the solid line represents the distance free energy profile from Fig. to the left of the minimum, and the free energy profile resulting from transformed probability (Eq. 6) from the contact reaction coordinate sampling (Fig. ) into distance space to the right of the minimum. The dashed line represents the converse process, where the distance profile from Fig. is used to the right of the minimum, and the transformed probability profile from the sampling in contact space is used to the left of the profile. As a visual aide, a simplified atomistic representation of the respective components is used as a background, with water oxygens and lipid heavy atoms following a standard color scheme (gray for carbons, red for oxygens in lipids, blue for the oxygen in water, and yellow for phosphorus).
