what is 'Res'? It should be a string with full path to the image
(i.e.,something like Res='/home/ce/data/mydata.img'). Then you will find
your image in that folder.

Without a path I guess your image will end up in your current folder,
but i am not sure about that.

Also make sure the scaling is not off when using spm_write_vol. In your
Vo handle, this is implicitely stored as the optimal intensity scaling
for your previous image, which might not be good for your new data.

Otherwise your code looks good to me.


Good luck,

Bas
