what is your setup? you want to compare within one subject? in a group
of subjects?

if it's just one subject, an easy solution consists in loading the STC
files for
both conditions in matlab, then do the difference and save the output
in a new stc file that you can visualize with mne_analyse. If you want to do
statistics that's a bit more complicated.

hope this helps

Alex
