The difference map is an option to compare glycomaps. Energy values of the second map are substracted from those of the first map, so that the user can see at a glance in which areas the maps differ from each other.
From the color scaling from red to blue it is obvious for each section of which map has the higher energy values and how large are the differences between the maps.
