[vtkusers] Error opening vtp file

[Isaac Castro Mateos]

Hi,

I am trying to read a vtp file with the  following code:

vtkSmartPointer< vtkXMLPolyDataReader > readerXML = vtkSmartPointer<
vtkXMLPolyDataReader >::New();
readerXML->SetFileName(paths.c_str());
readerXML->Update();
mesh = readerXML->GetOutput();

However, it is given me the following error:

ERROR: In
/staff/icm16/My_repository/Thirdparties/VTK-6.3.0/IO/XML/vtkXMLReader.cxx,
line 234
vtkXMLPolyDataReader (0x68f310): Error opening file
/staff/icm16/TestSamples/SegmentationVertebrae/SegmentationsNew/V1/meshWithSimilarityReg2.vtp


ERROR: In
/staff/icm16/My_repository/Thirdparties/VTK-6.3.0/Common/ExecutionModel/vtkExecutive.cxx,

  Registered Events: (none)
  Request: REQUEST_INFORMATION

There is no problem at all when opening the file with paraview. I am using
an Ubuntu machine with VTK-6.3.0.

Any idea what the problem could be?

Thanks a lot.
Isaac.
