[Paraview] DICOM series reader for Paraview

[Biao She]

Thanks for your help, Jerome.
I find the vtkGdcmReader files in the latest GDCM package. After I build
these files as a Paraview Plug-in and load it, I got this error message from
Paraview console:
ERROR: In
/usr/scratch/bshe/Paraview/ParaView-3.4.0/Servers/Common/vtkProcessModule.cxx,
line 1079
vtkProcessModule (0x8a7c2e0): Cannot create object of type "vtkGdcmReader".
while processing
Message 0 = New
  Argument 0 = string_value {vtkGdcmReader}
  Argument 1 = id_value {84}

ERROR: In
/usr/scratch/bshe/Paraview/ParaView-3.4.0/Servers/Common/vtkProcessModule.cxx,
line 1080
vtkProcessModule (0x8a7c2e0): Aborting execution for debugging purposes.
I must do something wrong, but when I build the vtkGdcmReader, no error
message at all. Here is my CMakeLists file:
FIND_PACKAGE(ParaView REQUIRED)
INCLUDE(${PARAVIEW_USE_FILE})

FIND_PACKAGE (GDCM)
IF (GDCM_FOUND)
   INCLUDE(${GDCM_USE_FILE})
ENDIF (GDCM_FOUND)

ADD_PARAVIEW_PLUGIN(vtkGDCMReader "1.0" SERVER_MANAGER_SOURCES
vtkGdcmReader.cxx)
ADD_PARAVIEW_PLUGIN(vtkGDCMReader "1.0" GUI_RESOURCE_FILES pqReader.xml)
ADD_PARAVIEW_PLUGIN(vtkGDCMReader "1.0" SERVER_MANAGER_XML reader.xml)

You also mentioned that you use vtkDICOMImageReader as your DICOM reader in
Paraview. It seems that I can only use the reader to read one DICOM image
file. How can I write the XML files for vtkDICOMImageReader to read a series
of DICOM files? Could you please email me your XML files for
vtkDICOMImageReader if possible? Thanks very much!
