[Insight-users] MetaImage: absolute path in ElementDataFile not working

[Luis Ibanez]

Hi Florian,

Thanks for sending our files.

I'm not sure that MetaImage can manage
filenames that have spaces in the path....


Your file is located at:

      "C:\Program Files\Data\MyData.raw"


Just to double check,
Please do the following

   Move your .mhd and .raw files to a directory
   without spaces. Something like:

       C:\itktest\MyData.mhd
       C:\itktest\MyData.raw


Try to read them from that location,
and let us know what you find.

If you can read the files then we
should probably fill a bug report
regarding filenames with spaces
and the MetaImage library.


    Thanks


       Luis
