[Insight-users] read raw images

[Leila baghdadi]

well, I think the error is telling you what is going on, the file name
you are providing does not match any of the suffices itk currently has!

if you are trying to read a raw image,

you need to have a tiny text header for it *.mhd (there is a sample file
in itk file format website),

The above file includes the name of the raw file *.raw
