Flowchart of LAD profile generation for the protein 5rsa:A. (a) Yellow ribbons display the secondary structures and red spheres represent the backbone atoms (N, Cα, C, O) of each residue. (b) The MSMS-generated triangular surface. (c) The simplified surface which is created by MeshLab. (d) and (e) are LAD profiles of the input protein for ED (LADED) and GD (LADGD) respectively.
