[FieldTrip] change radiological to neurological convention

[sibylle]

Hey Kathrin,

which SPM version are you using?

As far as I know spm2 uses neurological convention (right is right),  
while spm8 uses radiological convention (right is left).
So using spm8, the slice and ortho plots will 'seem' flipped, but you  
can check the Talairach coordinates to be sure.
Whereas in the surface plots, the right of the brain will appear on R  
side of image (maybe you could revert back to spm2 using T1.mnc  
template mri for sourceinterpolate..?).

Hope that helps!

Sibylle
