[Insight-users] ThresholdSegmentationFltkGui Runtime Error, Any Advice?

[William A. Hoffman]

This is a C++ exception.   You need a try catch block around the code.
You want to catch itk::ImageFileReaderException, you can then print out
the exception object.  My guess is that it does not have the correct path
or file format, but the exception object should tell you that information.

However the reason I think the problem is not related to the images is that I was running the ThresholdSegmentationLevelSetFltkGui application without a problem  w/ same images prior to this runtime error. One thing I forgot to include in the runtime error messages is the following:
