Dear Teiv, try to use vmtksurfacewriter instead of vmtkmeshwriter. The output of vmtkcenterlines is a polydata object.

I have used the following commands but it has not been successful: $ vmtkcenterlines -ifile aorta.vtk --pipe vmtkmeshwriter -ofile foo.vtk -mode ascii I really appreciate any help you can provide. Best, Teiv.

I just pushed a commit on the source code repository to allow this: ... --pipe vmtksurfacewriter -ofile foo.stl -mode ascii It works for stl, vtu, vtk, vtp, ply. If you're in a rush, get these two files https://raw.github.com/vmtk/vmtk/master/vmtkScripts/vmtksurfacewriter.py https://raw.github.com/vmtk/vmtk/master/vmtkScripts/vmtkmeshwriter.py and copy them over to your {installpath}/lib/vmtk/vmtk folder, replacing the old ones. Note, it's the lib folder, not the bin folder (you'll find two files called vmtksurfacewriter and vmtkmeshwriter, without the py extension: they're not the right ones to replace). Luca PS: Richard, thanks a lot for sharing the script, very much appreciated.

Attached is a perl script I've used for converting .off files to .stl -- should be trivial to adapt it to python/iterate over a vtkPolyData instead of .off input. -rd On 11/01/2012 01:40 PM, Vikram Mehta wrote: Hi Arjan, Thanks alot for your response. I seem to have got all the data I needed. On a separate note, Does anyone know how to save your surface file as an ASCII STL and not a binary one. Thanks alot ! Vikram.

Good luck with it, Arjan On Tue, Oct 16, 2012 at 7:58 PM, Vikram Mehta <vv...@gm...> wrote: Dear VMTK users, I have a surface reconstruction of a catheter within a coronary artery and have also generated the centerlines for it. However, for further processing, I need the coordinates of the catheter centerline and was wondering if you all had any idea to do this ? I tried using vmtkcenterlinegeometry but I might be doing something wrong, vmtksurfacereader -ifile /home/vm308/catheter.vtp --pipe vmtkcenterlines -seedselector openprofiles --pipe vmtkcenterlinegeometry -ofile catheter_clg.vtp Ideally I would like a .txt file (basically a point cloud) - is this achievable ? Please advise.
