Soma_Surface

Soma_Surface
This function computes the surface of the soma (Type=1). If the soma is composed of just one compartment, then it uses the sphere assumption, otherwise it returns the sum of the external cylindrical surfaces of compartments forming the soma. There can be multiple soma's, one soma or no soma at all.
Single Soma: 4 x PI x r 2
   (Area of Sphere)

Multiple Soma: 2 x PI x r x h
   (External Surface area of Cylinder)




Function Output Type : Numeric

Calculated : At Soma Point

Command Line Usage Function : "-f0, 0, 0, 10.0"

Output:
Metric Total_Sum #Compartments
(considered)
#Compartments
(discarded)
Minimum Average Maximum S.D.
Soma_Surface 387.775 1 (1101) 387.775 387.775 387.775 0
*All units are in microns

Output Interpretation :

Soma_Surface is computed with the help of two mathematical formulas.
For single soma: 4*(pi)*(r^2).
For multiple soma: 2*(pi)*(r)*(h).

Since there is just one compartment, the Total_Sum, minimum, average and maximum values are all the same. If the soma consists of more than one compartment, then the correct value of the surface of the soma would be returned under Total_Sum.
