Meaning of axon and dendrite nodes?

[dbrnz]

Attached are PDFs for the Ardell Armour connectivity graphs, with red nodes indicating that some term of the node's identifiers is in the list of dendrites for the path; green nodes indicating that some term of the node's identifiers is in the list of axons; and grey nodes indicating that the node's identifiers are in both the list of dendrites and the list of axons.

Some paths (eg. ardell-1 and ardell-4) are straight forward; others not so. Is this as expected?

I'm assuming these are only for terminals? If so there should be no gray cases, see the comment at the end about why I think this is happening (need to check topology).

Here are the ones that look correct to me:

1
4
12

Some issues:

5 should not have a dendrite in the white matter
6 missing left atrium, bad edge between ventricles
  missing axon terminal in epicardium
7a 7v 8a 8v no axon terminals in the ganglia, nor epicardial fat
9a 9v no dend terminals in the ganglia, nor epicardial fat
11 no dend terminal in epicardial fat (fixed on my end already)
13 I think the dend in epicardium is right for the wrong reason
   missing pair of terminals (should be 4 only see 2)

I think I know why the dendrites/axons are sometimes too long, it is because we have to check the type and the topology because the way that chains are generate will put the -bag material on lyphs that are tubes.

Looks like the reason is because the axon/dendrite matching only returns regions not region-layer pairs.
