Taper_2

This function returns the Hillman taper. This is measured between two bifurcation points.

Function Output Type : Numeric
Calculated : At Every Branch
Output:
Metric | Total_Sum | #Compartments (considered) |
#Compartments (discarded) |
Minimum | Average | Maximum | S.D. |
Taper_2 | 10.7164 | 85 | (1017) | -0.333 | 0.126 | 0.8636 | 0.2235 |
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.
