Fractal_Dim

Fractal dimension metric is calculated
for branches of the dendrite trees.
Formula: (n-1) Σ( e i p i ) - Σ( e i ) Σ( p i )
(n-1) Σ( e i 2 ) - (Σ( e i )) 2
( e i is EucDistance and p i is PathDistance)
(n-1) Σ( e i 2 ) - (Σ( e i )) 2
( e i is EucDistance and p i is PathDistance)
Function Output Type : Numeric
Calculated : At Every Branch
Output:
Metric | Total_Sum | #Compartments (considered) |
#Compartments (discarded) |
Minimum | Average | Maximum | S.D. |
Fractal_Dim | 70.9621 | 74 | (1423) | 0.61505 | 0.95894 | 1.02758 | 0.0642655 |
Output Interpretation :
Total_Sum = 70.9621 gives Total_Sum, Minimum =
0.61505 gives minimum, Maximum = 1.02758 gives maximum for given input
neuron.
References :

The
Branch needs at least 3 compartments or 4 endpoints to compute the
Fractal_Dim.
