right click on datanode
Preview works!! but as soon as you click OK you get either NOTHING or ALL as segmentation.
With other double images (e.g. Range from 0.0 to 127.0) it SEEMS to work..

Before that TKThresholding function is called, the image is still a float image. Maybe in this function the casted ITK image is not float anymore??? or it is float but the pixel intensity was rounded to integer during casting??
