For some neuron populations such as splen-5 in rat and pig, neuron connectivities are incorrectly rendered when direct lines are drawn between nodes. In splen-5, it seems that these nodes are identified as being connected to the centerline connecting the splenic_branching_point and the celiac ganglion - superior mesenteric ganglion complex (Figure 1).

In order to get the correct results (Fig 2), I play around with variable max_score at:

but I believe this is not an appropriate approach.

Thanks
