Figure 7
Scheme of the fold-extraction algorithm. The external graph represented in a circular layout is the forest of tree searches that are maintained in the memory by ALEPH during extraction from a target structure (PDB entry 3to7). Each layer of the circle is coloured with the same colour as the template fragment (from PDB entry 4e1p) to extract. The light-blue β-strand is the first fragment to be found, followed by the second, purple β-strand and finally by the helix. Leaves in the external layer represent solutions satisfying all geometrical constraints according to the thresholds set (60% for intra-vectors and inter-vectors). The half matrix displays the three fragments (compacting their lengths), showing triangle areas, coloured the same as the fragments, that carry the internal properties of each fragment and square areas where the geometrical relationships between two fragments are displayed using a colour gradient. |
