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

[Luis Ibanez]

Hi Florian,

Could you please post the *exact* absolute path that you were using
when you encounter this problem ?

We are able to read files with absolute path without any problem.
It is therefore likely that there is something special about the
path that you were using.

Also, please let us know what platform are you using.


    Thanks


       Luis
