[Insight-users] Convert NRRD into DICOM

[Luis Ibanez]

Hi Ezequiel,


     If your input file is in NRRD format,
     why are you passing a RAW format as input ?


ITK is expecting that a NRRD file will be called

               LTS_IMG05.nrrd

not to be called:

               LTS_IMG05.raw



Also, is this image 2D or 3D ?


You may have to retouch the example code in order
to manage 3D images.


    Regards,


        Luis
