[Insight-users] Help with the template matching : : Problem connecting VTK and ITK

[Luis Ibanez]

Hi Longfei,

Can you please give us more information on what you
meant by "the initialization of the program is failed"  ?

Is it producing a segmentation fault ?
Is it throwing an exception  ?
Is it producing incorrect output ?

Does it produces any error message ?

Did you tried adding a try/catch block around your code ?



Thanks


   Luis
