    Representation of the proteins as a points in 3D
based on similarities of their interaction fields.
    The distance between proteins i and j is defined as
D(i,j) = sqrt(2-2*SI(i,j)), where SI(i,j) is the
similarity index of their interaction fields. Four
points defining the 3D space were chosen as follows:
    a) The first two points (1 and 2) are chosen as
those for which the distance D(1,2), is largest. This
D(1,2) is then used for normalization of all other
distances.
    b) Point 3 is chosen so that the area of the
triangle formed by points 1,2 and 3 is the largest.
    c) Point 4 is chosen so that the volume of the
tetrahedron formed by points 1,2,3 and 4 is the largest.
    The 3D coordinates assigned to these 4 points are
(0,0,0), (1,0,0), (a,b,0), (c,d,e), where a, b, c, d
and e are computed unambiguously from the 6 pairwise
distances.  The other compounds are projected onto this
defined 3D space with coordinates determined from their
SI(i,j) values.

    This representation is approximate and distorts
original distance matrix.  Accuracy may be measured
by similarity of the original matrix to the matrix
derived from 3D distribution; Hodgkin index of this
similarity is :    0.810
(more accurate means this index close to 1.000)
