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

Hello Luca,
Could you please show me a way to output the result of the vmtkcenterlines
command in the Ascii format so as it can be read by Gmesh.
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.

Hi everyone,
about the STL thing, the vtk writer used in vmtk supports ASCII files out of
the box, only
I haven't exposed that option at the script level until today.
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.

Personally, I write my stl files myself, because I build my surfaces in
another program. 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.

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.

Hi Vikram,
You could try this:
vmtksurfacereader -ifile /home/vm308/catheter.vtp --pipe vmtkcenterlines
-seedselector openprofiles -ofile catheter_cl.dat
It should give you the coordinates of the centerline points in a
human-readable format.
Good luck with it,
Arjan

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.
Looking forward to your replies
Thanks in advance,
Vikram.
