Extended Data Fig. 4: Proofreading with the ChunkedGraph.

(a,)In the ChunkedGraph connected component information is stored in an octree structure where each abstract node (black nodes in levels >1) represents the connected component in the spatially underlying graph (dashed lines represent chunk boundaries). Nodes on the highest layer represent entire neuronal components. (b) Edits in the ChunkedGraph (here, a merge; indicated by the red arrow and added red edge) affect the supervoxel graph to recompute the neuronal connected components. (c) The same neuron shown in Fig. 2 after proofreading with each merged component shown in a different color. Scale bar (c): 10 μm.
