[Insight-users] Re: vtkview and files converted by ITK

[Perrine Paul]

Hello Luis,
I have changed the unsigned short pixel type in unsigned char.
The results are:
For GIPL, I have the same problem when I tried to read again the file I
created with unsigned char. 
ImageReadWrite mynewimage.gipl mynewimage.gipl
I have the same error:
itk::ExceptionObject (0x8092ee0)
Location: "Unknown"
File: /usr/local/src/InsightToolkit-1.8.0/Code/IO/itkImageIOBase.cxx
Line: 121
Description: itk::ERROR: GiplImageIO(0x80929c8): Unknown component type:
0

For Analyse:
Vtkview accepts to read and dispaly these analyse files, but when I want
to perform registration:
 
Start registration: ERROR: In
/staff/th04/project/linux/vtkCISG/objects/library/CISGRegistration/vtkC
ISGRegistration.cxx, line 778
vtkCISGFFDRegistration (0x804f1b8): ::Run: target must be SHORT image

Thank you for your help.
