[Insight-users] it works just once!

Hi Heros,

Are you invoking "Update()" in the filter
after you change the input ?

The filter will not execute until you invoke
Update() or UpdateLargestPossibleRegion().

Maybe it will help if you post a more complete
piece of your code.



    Thanks


      Luis
