<p>Hi Martin,</p>
<p>there is currently no optimization specific for 4x1 electrode
positions. The closest you can get is to optimize with: <br>
</p>
<p>max_total_current: 2 mA</p>
<p>max_individual_current: 1 mA</p>
<p>max_active_electrodes: 4</p>
<p>and for the target:<br>
</p>
<p>directions = None<br>
<br>
and then try several values for the <span class="n">intensity of
the target.</span><span class="o"></span><span class="mf"></span></p>
<p>Best regards,</p>
<p>Axel</p>

<p class="MsoNormal">Hello, <o:p></o:p></p>
<p class="MsoNormal">This is Martin B, a University of Calgary
researcher using simnibs tdcs optamization modeling for my
project. Thank you for the fast response on my last question.
I was now wondering if there was any way to optimize the
electrode placement for a 4x1 montage, where you could set one
anode or cathode to be at +/- 1 mA, and 4 adjacent ones at -/+
0.25mA, but with an optimized position.
