Hi Manasi,
The not-so-elegant solution to your problem may be here:
http://sourceforge.net/mailarchive/message.php?msg_id=28032510
Open the file .\vmtk 0.9.0\lib\vmtk\vmtk\vmtkcenterlinegeometry.py in a
text editor and add the following lines near the end of the file:
centerlineGeometry.SetLengthArrayName('Length')
centerlineGeometry.SetTortuosityArrayName('Tortuosity')
Run the following in PypePad to get the desired output:
vmtkcenterlinegeometry -ifile cl.vtp -smoothing 1 -iterations 10
-outputsmoothed 1 -ofile clgm.tec
Notice that you should leave out of your script "-lengtharray Length"
and "-tortuosityarray
Tortuosity",because those array names are now hard-coded. Otherwise, you
will receive again the error message: "vmtkcenterlinegeometry error:
unknown option -lengtharray"
Optionally, you could leave out "-curvaturearray Curvature", because the
default value is 'Curvature'.* *And you could leave out "-i
Centerlines", because
you already specify the centerline with "-ifile cl.vtp".
Hope this helps,
Arjan
