# The two lines below instruct PLUMED to calculate the distance between # the adsorbate and the isosurface. Notice how, as discussed in the main text, # only a subset of the atoms in the membrane are used when we calculate the # density as this reduces the computational expense.cont:DISTANCE_FROM_CONTOUR...Calculate the perpendicular distance from a Willard-Chandler dividing surface.

In order to reduce the # computational expense this bias is stored on a grid.
