The graphical representation of pairwise distances between all C-alpha atoms can give you hints about:
* the architecture of the protein structure * the contacts between secondary structure elements * detection of domains in the structure * the beauty of protein structures in 2D Rows are active links providing the residue pop-up menu and can take you to other tools. ==== References ==== Richardson, J.S.
