meg_stc_morph:
how bad is it?
spatial problems
statistical problems meg_stc_morph now infamous intersubject averager
there are some problems
it’s not that bad, at least qualitatively

MNE Movies: MNE Movies EasyMEG does a great job of rendering movies
But sometimes for talks we may want to show more
Can use a combination of programs to make custom movies
MNE Movies: MNE Movies meg_snapshot_om  make pictures
for every frame and every view
photoshop
adjust contrast and put frames together
matlab (showtime toolbox)
control timing and make movie
MNE Movies: MNE Movies meg_snapshot_om  make pictures for viewname in 'lat med ven'
do
meg_snapshot_om \
--frameopt '0 10 10 20 20 30 30 40 40 50 50 60 60 70 ...'
done
