Hi,

I would like to see a straightened vessel in vmtk. To do it I tried with the sample dataset following commands:

vmtklevelsetsegmentation -ifile Aorta_voi.mha -ofile Aorta_level_sets.vti

vmtkmarchingcubes -ifile Aorta_level_sets.vti -ofile Aorta_level_sets.vtp

vmtkcenterlines -ifile Aorta_level_sets.vtp --pipe vmtkcenterlinegeometry --pipe vmtkcenterlineattributes --pipe vmtkimagecurvedmpr -ifile Aorta_voi.mha

But, when I try to run the last line, I get the error message:

Executing vmtkimagecurvedmpr ...
ERROR: In ../Common/DataModel/vtkImageData.cxx, line 1324
vtkImageData (0x7fd9056e8b50): No Scalar Field has been specified - assuming 1 component!

I have also saved the center-lines and display them and they look fine.

Please let me know what I am doing wrong.

Kind regards,

Konrad

Hi Konrad,

assuming you still need this to work, I just pushed a fix. You'll have to build vmtk from scratch for the time being.

Best,

Luca

I got the same error but in different script, my script is:

myargs = 'vmtkcenterlineresampling -length 0.01 -ifile centerline.vtp --pipe vmtkcenterlineattributes' \
         ' --pipe vmtkcenterlinegeometry --pipe vmtkimagecurvedmpr -ifile data.vti -size 1000 ' \
         '-spacing 0.01 -ofile reformat.vti --pipe vmtkimageviewer '
mypype = pypes.PypeRun(myargs)

what is the problem?

Hello.

I am having the same problem. I have also tried using the data from the previous question https://groups.google.com/forum/#!searchin/vmtk-users/vmtkImageCurvedMPR%7Csort:date/vmtk-users/fugTpK2L_AY/jUhZXYNeCgAJ, however I am still having the same problem:

ERROR: In ../Common/DataModel/vtkImageData.cxx, line 1324
vtkImageData (0x33d2660): No Scalar Field has been specified - assuming 1 component!

Have you found a way to solve the problem ? Am I missing something (I am using the same script) ?

Any clue will be very helpful.

Best,

Valentina
