Max Euclidean Distance
The maximum Euclidean distance of all nodes. Euclidean distance is the straight line distance from the soma (root) to the node.
Number of Stems
The number of stems attached to the soma. When the type of the node is not soma, it is labeled as a stem.
Number of Bifurcations
The number of bifurcations for the given input neuron. A bifurcation point has two daughters.
The average ratio between Euclidean distance of a branch and its path length. Euclidean distance of a branch is the straight-line distance from the soma to the branch. Path length is the sum of the lengths between each node along the path.
The average ratio between the diameter of a daughter branch and its parent branch. One value for each daughter branch is generated at each bifurcation point.
