Hi, tomdeol.
Thanks for your great work!
When I use the "Segment the segments" in toolkit. Two errors when I deal with different dicom sequences.

1. The plugin PTKPulmonarySegments failed with the following error: Error in function SeparateSmallestBranchByRadius: Could not subdivide the tree into exactly the desired number of branches.
2. The plugin PTKPulmonarySegments failed with the following error: Attempt to access sample_image(16,18,29)；As size(sample_image)=[2,2,2], is out of range。
   Thanks
   Gu Yu.

Hi, thanks for posting the issues. The pulmonary segment algorithms are quite experimental and don't always work. They are based heuristically on analysis of the branching airway tree, and error 1 is really saying that the heuristic isn't clever enough to work out what's going on in this particular tree.

The second error might be a bug — I'll look into this and update here if I find anything that can be improved. Thanks!

Hi, tomdeol.
Thanks for your great reply!
If you decide to update this excellent toolkit, I suggest that you can add the function of lung boundary repairing if there are the juxta-pleural lung nodules appeared in lung boundary.
You can see the paper “Automated detection of lung nodules in CT scans: Preliminary results” .
I would trouble you when I have other questions. Thanks for your help！
