Thanks for your reply Yaniv! That is how I initially tried loading the NIFTI volumes (via the GUI, File|Load), but in the meantime I discovered what the problem was: there were spaces in the name of the folder  containing the image, and apparently non-Windows OSs such as Xubuntu don't deal well with that!

For future reference, as soon as you eliminate spaces - as well as possibly other'forbidden' characters from the file/folder name, FreeView will load the image with no problems.

Hi Tudor,

I am not very experienced with Freeview, but did you try typing "freeview" in the command line and using the File->Load Volume… from the GUI?
If that doesn't work maybe you can give me the exact command you used.

Hope I could help.
Regards,
Yaniv
