Figure 9: Probability of lipid tail protrusion of lipids that are in contact with the peptides.

Lipid protrusion was assumed to occur when any carbon in the lipid tail protruded more than 0.1 nm beyond the phosphate group. Only the lipids which were within a distance of 0.5 nm from the peptides were included in the calculation. The plots shown correspond to a weighted average over all the microstates (the weight of each microstate was obtained from its free energy). The errors were calculated as described in Fig. 7.
