Terminals (branched structure analysis)

Purpose

Terminals analysis distinguishes between segments that lead to a node and segments that lead to a termination.

Analysis results

Tree: Each tree selected for the analysis is assigned a unique number starting at 1.

Type:

• Terminal: Segment ending in a termination.
• Node: Segment ending in a node.

Quantity: Number of segments of a given type.

Length total: Sum of all of the lengths of the segments of a given type.

• Mean = [Length total] / [Quantity]
• Variance: Computed using the individual lengths and the mean.

Surface total/Volume total: Computed by modeling the segments as a series of frusta (truncated right circular cone).

• Mean = [Surface or Volume total] / [Quantity]
• Variance: Computed using the individual surfaces or volumes and the mean.

Spines: Total quantity and quantity broken down by spine class.
