[Insight-users] Convert signed short to float in DICOM

[Xavier Mellado Esteban]

   Hi Goo:

   Write images in each step of your pipeline, before and after use each 
filter. And find exactly which is the problem an report here more 
information.

   If you have problems with casting, there are filters for doing this, 
see ITK User Guide (http://www.itk.org/ItkSoftwareGuide.pdf) Chapter 
6.3. Look at Geodesic Active Contours example (9.3.3) and 
GradientMagnitudeRecursiveGaussianImageFilter example (6.4.2), too.

              I hope this helps you:
                                                  Xavi
