| Abstract
| - We consider numerical characterization of proteomics maps by representing a map as a three-dimensionalgraphical object based on x, y coordinates of the spots and using their relative abundance as the z coordinate.In our representation the protein spots are first ordered based on their relative abundance and labeledaccordingly. In the next step a 3-D path is constructed connecting spots having adjacent labels. Finally amatrix is constructed by assigning to each pairs of labels (i, j) matrix element, the numerical value of whichis based on the quotients of the Euclidean distance and the distance along the 3-D zigzag between the twopoints. The approach has been illustrated on a fragment of a proteomics map and compared with 2-D graphicalrepresentation of proteomics maps.
