Soma_Surface
This function returns the Hillman taper. This is measured between two bifurcation points.
Formula : D a - D c

D a




Function Output Type : Numeric

*All units are ratios

Output Interpretation :

Hillman taper: given a branch it computes ratio between the final diameter (Da) and the initial one       (Dc) = (Da - Dc)/ Da.

Total_Sum = 10.7164 gives Total_Sum, Minimum = -0.333 gives minimum, Maximum = 0.8636 gives maximum for given input neuron.
