<p class="MsoNormal">Hi all,<br>
<br>
Just had a brain wave, I'll share it for people with similar
situation that might be interested in this thread. I think I
should just get a random structural MRI that extends lower
(includes ears and bit below), optimally of a subject with a
head similar to the MNI template. Make a BEM model (hmm,
have to fix these errors I mentioned earlier then, well,
should be doable on linux using dipoli). Then use
ft_electroderealign to align the electrodes to this MRI, do
the source analysis for all subjects using this model, and
subsequently use ft_volumenormalise to normalize to MNI
template if I want to use any atlas functionality.<br>
<br>
If anyone did this already using FieldTrip and has a
pre-made BEM (just like the standard_bem), would be really
nice if you're willing to share :)
<br>
If not, I'll make my own, and people with low electrodes and
no structural MRI and or no linux access can email me if
they want to use it.<br>

<p class="MsoNormal">Hi Lilla and Imali,<br>
<br>
Thanks for your replies. In my case, the problem is not
the aligning. My nasion electrode is on the nasion, and Cz
is on Cz, everything is where it should be. The EGI 128
electrode net really has these low electrodes, which are
there specifically to make source analysis better by
capturing more of the electric field. So I would have the
best solution if I'd leave them there. However, in the
model as derived from the MNI template, the skin part does
not go down low enough.<br>
<br>
I looked at the picture after ft_prepare_vol_sens (see
attachement, black is before, red is after), and indeed,
this is not good. The low electrodes are squeezed up, and
this will make source analysis worse. So I should indeed
remove these electrodes (which is a pity), or find a
better MNI template.<br>
<br>
<b>So my question is:</b><br>
Does anyone know of a template in MNI space that extends
more down? This template comes from SPM8, is there a
version that extends lower? Or could I extend the skin
roughly downwards with some triangular magic?<br>
<br>
I'm also a bit confused about the statement on this wiki
page: <a moz-do-not-send="true"
href="http://fieldtrip.fcdonders.nl/template/headmodel?s%5b%5d=standard&s%5b%5d=bem">http://fieldtrip.fcdonders.nl/template/headmodel?s[]=standard&s[]=bem</a><br>
under "revision information" header "skin" is says: "This
skin surface is not used in the BEM model itself for
computational reasons, but can be used for visualization."<br>
But this does not seem to be the case, since my electrode
positions are modified based on till where the skin goes.
So the skin surface does significantly influence the
source analysis.
<br>
<br>
Anyway, thanks for all the help, and worse case, I just
get rid of the low fellows.<br>
<br>

<p class="MsoNormal">hi Ingrid and Imali, <br>
<br>
<br>
I think it is a really good question what to do in
Ingrid's case. I do not know the "right" answer, but I
would like to share my thoughts about it.
<br>
<br>
The ft_prepare_vol_sens is indeed projects the electrode
positions closer to the headsurface as Imali wrote. But
this function called automatically when you create your
leadfield, so you do not have to do it separately (unless
you want to visualize the corrected electrode positions).
<br>
<br>
However, I have been advised to rely on this projection
carefully if electrode positions are far from the skin and
specially, if the inaccuracies (distance from the skin)
are not equally distributed across the electrodes, because
that can cause a spatial bias.
<br>
<br>
Therefore, my question would be: why are those electrodes
so low? Are those positions reflect the actual positions
of the electrodes during the measurement? If yes, I would
not change their positions, I would rather try to extend
my headmodel e.g. by using another template. (or another
(but quite suboptimal) possibility is maybe to exclude
those electrodes (and the data) from the analysis if they
are anyway far from the brain.)
<br>
<br>
If the position of the electrodes should be higher up on
the head, then instead of relying on projection, I would
try first to scale the electrodes to fit them into the
headsurface with the ft_electroderealign function.
<br>
<br>
I looked to the standard_bem file in the template
directory, and I also load in the standard_1020.elc, and
those electrodes perfectly fit the vol. So, it seems that
the extension of the standard bem headsurface is suitable
for the area which is covered by the those template
electrodes. And I do not know if the electrode set you use
should cover a larger surface of the head, or if it should
be just adjusted to the given headsurface.

I used the ft_prepare_vol_sens as, <br>

without MRI <br>
<br>
Hi all, <br>
<br>
A follow up on this and some new issues: <br>
<br>
1) I first tried Jörn's approach by creating my own BEM,
always fun to <br>
make it yourself ;) However, I did not succeed since: <br>
a) the dipoli method does not work on Windows <br>
b) I downloaded the openmeeg toolbox, but got an error
"om_minverser.exe <br>
has stopped working" I've emailed their buglist <br>
c) bemcp did run, but the result was not ok (see
attachement). I also <br>
got the warning "% Warning: Matrix is singular, close to
singular or <br>
badly scaled. Results may be inaccurate." several times,
so that might <br>
be the problem. <br>
d) and asa gave the following error: % Error using
ft_prepare_headmodel <br>
(line 201) % You must supply a valid cfg.hdmfile for use
with ASA headmodel <br>
<br>
And away went my determination to do it myself, so I
continued using <br>
thestandard_bem.mat <br>
<a moz-do-not-send="true"
href="http://fieldtrip.fcdonders.nl/template/headmodel?s%5b%5d=standard&s%5b%5d=bem"><http://fieldtrip.fcdonders.nl/template/headmodel?s[]=standard&s[]=bem></a>.
<br>
(I did not know this existed, I've added this link to note
in the <br>
headmodel tutorial <br>
<a moz-do-not-send="true"
href="http://fieldtrip.fcdonders.nl/tutorial/headmodel_eeg?&#background"><http://fieldtrip.fcdonders.nl/tutorial/headmodel_eeg?&#background></a>
to
<br>
make it easier to find, thanks Tzvetan for pointing this
out!). <br>
<br>
2) This worked and after some fiddling to get the
electrodes aligned it <br>
looks okay (see attached). <br>
However, as you can see in the figures, I have several
very low <br>
electrodes, that are lower than the skin mesh. So I was
wondering if <br>
this is a problem? Since for accurate calculation of how
the currents <br>
flow from these low electrodes, I assume one needs the
skin to go till <br>
there? What happens when I have electrodes floating in
thin air? <br>
*So my question is:* <br>
a) will this cause great inaccuracies? <br>
b) if so, how can I extend the skin to go lower? The
template MRI only <br>
goes that far to the bottom... Trick anyone? <br>
<br>
Thanks again, <br>
Ingrid <br>

<br>
in addition to Jorn's approach since you don't have MR and
digitized <br>
elec position's you can load and realign the electrodes to
the <br>
standard bem. Subsequently you can calculate the lead
field and <br>
continue with your analysis pipeline. <br>
