[Insight-users] ITK DICOM series reading

[Elhassan Abdou]

 Hi John

I built a UI system with QT and the creation of bonesegment class is carried by an action so i am sure that the path I sent to reader is correct I even tried the same path with vtkDicomReader and it works fine. 
I also tried to make the path hardwired and it does not work. I am using itk 4.2

Please help this problem is driving me crazy
best

Are there any series found? The reader will not be happy if fileNames is empty.
