[Insight-users] AddImageFilter problem...

[Joshua Cates]

Hi Sergio,

It will help if you let us know what error
you are getting. 

I would suggest enclosing your Update() 
calls in try/catch blocks.  You can print
any exceptions that ITK throws.

For example,

try {
myFilter->Update();
}
catch (itk::ExceptionObject &e)
{
std::cerr << e << std::endl;
return ERROR_CODE;
}

Josh.
