[Insight-users] GaussianFilter

[Stephen R. Aylward]

Hi Samuel,

I don't know if you sent me the file that you've been using, but in the 
file you sent me, the last line of the .mha file reads

ElementDataFile = brainweb1.raw

So, the MetaImage reader is looking for your data to be in a file called 
"brainweb1.raw"

Try using this file and renaming your "brainweb1e5a10f17.raw" file to 
"brainweb1.raw" and let us know what happens.

Thanks,
Stephen
