Hi Lilla,

Also, note that you can readily use the spherically symmetric  
conductor model in the forward calculation by using  
mne_forward_solution directly rather than the mne_do_forward_solution  
wrapper script.

Unfortunately, there are no volume data visualization tools in MNE.  
You need to use the FreeSurfer tools for this.
