tree_morphometry — GRAPH tree op

• 資料種類:table → table

• 呼叫: import fullseye as fs; fs.ledger.tree_morphometry(tree)(要直接呼叫實作,import treemorph; treemorph.tree_morphometry(tree);從台帳取用則 opsgraph.get("tree_morphometry"))

用法

> 該運算子的說明尚無譯文,以下照原文給出。

Counts and lengths of a tree table (from tree_from_swc).

Returns nodes, edges, bifurcations (nodes with two or more children), tips (nodes with no child), cable_length (sum of segment lengths), max_path_length (longest root-to-node path along the tree) and max_radial (largest straight distance from the root).

Identities (checked inside, fail-closed): nodes == edges + 1, and tips == 1 + sum(children - 1) over the nodes that have children — tips are counted from the child counts directly, the right side from the branching nodes, so a bug in either count breaks the equality. A root with one child is not a tip.

Raises ValueError: not a tree table (see tree_from_swc).
