as a second link I meant to paste this one:<br>

The procedure, however, is in more detail explained in the first
link I pasted, in this tutorial an example of how to use that is
illustrated. Hope it works out!<br>

<p style="margin-top: 0; margin-bottom: 0"> I need to ask for
a helpful hint on MNE source reconstructions. Following
this tutorial <a moz-do-not-send="true"
href="http://fieldtrip.fcdonders.nl/tutorial/minimumnormestimate">http://fieldtrip.fcdonders.nl/tutorial/minimumnormestimate</a> I obtained
nice individual cortical meshes and source points; the
MNE forward and inverse solution for the individuals all
work well. I would now like to normalize the individual
grids to a template brain in order to do statistics and
averaging for plotting. I figured out that I could use
ft_sourceinterpolate to tranform the grid into a volumetric
representation, and then use ft_volumenormalise to normalise
to a standard brain. But this did not work too well
for source structures containing time series (like
'mne'-stcutures) where the computational load gets very
high. I also tried to use a grid of one subject as a
template for the other subject's grids with
ft_sourceinterpolate and cfg.interpmethod = 'smudge', but
this seems to require two grids with the same number of
source points as input(?). </p>
