Mitochondria Skeletons- longest shortest path

Hello Everyone,
I’m using image j to create skeletons of mitochondrial networks. A parameter I’m confused about is the longest-shortest path. It gives me a white skeleton with some parts that are magenta. What do the colors mean? What really is the longest-shortest path in simple terms? Is it just the full continuous path? Then what do the colors mean in this regard?

Thank you!

I’m assuming you are using AnalyzeSkeleton to do your measurements? There is a short description of the largest shortest path on that site… and says “the skeleton in white and the shortest path in magenta… the largest-shortest path is calculated using the Floyd-Warshall algorithm - it’s only calculated if you select it as an option. This blog post explains the algorithm pretty well…
