<br>
</small></small><small><small>Thank you for the sharing the
information. <br>
<br>
Before trying to 're-invent the wheel', might it be possible for
Fieldtrip to incorporate the famous Schoffelen et al., 2008's
cerebellar-included MRI template for visualization purpose --
with the awareness that it will not permit inflation? Unless my
limited knowledge on brain graphics has prevented me from
appreciating the importance of 'inflation' within the Fieldtrip
coding environment; in which case, I hope to be enlightened, if
it is within anyone's knowledge.<br>
<br>
Also, does the 'isosurface' function preserve the MNI
coordinates, if I should try to create my own template?<br>
<br>
Many thanks, again! And Happy Easter to all.<br>
May<br>
<br>

<div>For the figures in the famous Schoffelen et al 2008 paper
(Neuroimage) I created the surfaces (with cerebellum) using a
segmented template MRI (using SPM) and then, after some image
processing (smoothing filling etc), called the matlab isosurface
function. This gives a triangulated surface which can be used
for visualization. Note that this procedure does not yield
topologically a sphere, so it cannot be used for inflation.</div>

<br>
I was wondering if there exists within the folders of
Fieldtrip, surface source-plot MRI templates which
includes the cerebellum, and if not, how could one
create a template which consists of the cerebellum, too?<br>
<br>
Any help would be gratefully appreciated!<br>
<br>
Thanks.<br>
