[Insight-users] I hope ITK read data from matlab , what should I do ?

[Samuel Pichardo]

You could use Python to make the link between Matlab file and VTK

read the file with numpy with
http://docs.scipy.org/doc/scipy/reference/tutorial/io.html


  and save in VTK through the VTK wrapper

https://code.google.com/p/devide/wiki/NumPyToVTK

be sure of saving the Matlab file with -V6 option
