To trace through such black spills one must scroll through the 2D a number of times adding and removing segments leaving a gap if needed until the neuron is extended to the cube's wall (if that is possible). Sometimes like tracing through mergers leaving a gap is required because adding a segment in the black spill might also add a portion of another neuron which is not desired. It may not look pretty in the end but it may be correct.
