Taper_2

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

Function Output Type : Real

Calculated : At each bifurcation point

Returns a value : For each branch

Command Line Usage Function : "-f21, 0, 0, 10.0"

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

*All units are ratios

Values to consider : All

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.
