Dear Lucia,
in fact the script only outputs the vtkMatrix4x4 VTK object, which is meant to
be used by other scripts, but not really to be ispected visually.
I now added this possibility in the git repository, however you might be
running the 0.9 release, in which case you need something different.
There are a few ways in which you can access the matrix elements, for instance
you could use a dummy script. Find it attached: just place it in your working
directory and go
vmtkicpregistration -ifile surface1.vtp -rfile surface2.vtp --pipe vmtkdummy
If there are no python import issues, you should see the matrix being printed
at the console.
Other ways involve using vmtk scripts from Python (see the advanced pype
tutorial) or simply modifying the vmtkicpregistration.py file in your
lib/vmtk/vmtk install directory and adding a
print self.Matrix4x4
statement at the end of the Execute method.
Hope this helps.
Best regards
Luca

All of the data generated in your IT infrastructure is seriously valuable.
Why? It contains a definitive record of application performance, security
threats, fraudulent activity, and more. Splunk takes this data and makes
sense of it. IT sense. And common sense.
