Schematic representation of the directions and norm of the orthogonal projection of genes used to compute Cd. Gene g3 will have the highest value of Cd as its position is close to the direction and far away from the origin. Gene g1 will have the second highest value of Cd. Gene g2 will have a negative value of Cd. Genes g4 and g5 will have values of Cd close to zero.
