Figure 1

The mapping of (a) secondary structure states (helix, strand and coil) and (b) solvent accessibility to a 2D SOM trained using 15-residue windows of sequence profiles. The size of the circles is proportional to the number of times a sequence window having a particular secondary structure state is mapped to that position. The most populated helix and strand locations are almost non overlapping, while coil is found in most parts of the SOM and are somewhat avoiding the most popular helix locations. The total number of points in the three plots is 360 000 (130 000 in helix, 70 000 in strand and 160 000 in coil).
