 __Note__ that the reported distances are Euclidian distances. In reality, the cross-linker will have to follow the
 surface of the molecule which might results in a longer effective distance. A proper comparison would require
-calculating the surface distance instead. Such an analysis can be done with the [XWalk][link-xwalk] or [jwalk](http://jwalk.ismb.lon.ac.uk/jwalk/){:target="_blank"} software.
