![vtp no points](https://discourse.itk.org/uploads/default/original/2X/f/ffd4ef5924d7c19f8008fdc5c4c4eed7032667e8.png)

Centerline.tre file created correctly. But there is no points in BranchCenterline\_0.fcsv file. We got message in log that is “BGFDG\_vtkMRMLModelNodeH.vtp does not contain coordinate system information” .

I have attached centerline.tre and branchcenterline.fcsv file for more information.
