<p>Dear Elene,<br>
</p>
<p><br>
</p>
<p>Looking at the structure of "electrodes", I see that there is no information about the units. Do you know in which unit this electrodes are expressed? How did you generate this structure? If I see correctly in the code ft_plot_sens assumes "mm" if no unit
is specified. This means your electrode structure is not expressed in mm.<br>
</p>
<p><br>
</p>
<p> As the unit information is missing, <span style="font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 16px; background-color: rgb(255, 255, 255);"> </span><span style="font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 16px; color: rgb(33, 33, 33); background-color: rgb(255, 255, 255);">ft_convert_units
will not work on your electrodes.</span> So you should add this information to the structure, and then you would be able to use <span style="color: rgb(33, 33, 33); font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 16px; background-color: rgb(255, 255, 255);">ft_convert_units.</span><br>

<div>Dear fieldtripers,</div>
<div><br>
</div>
<div>I am tryng to visualize the electrodes and the headmodel at the same time. The problem that I have is that I need to reescale one of them.</div>
<div><br>
</div>
<div>I have tried to function ft_convert_units, but I just obtain the image attached. </div>
<div><br>
</div>
<div>The structure of the information are the next ones,</div>
<div><u>headmodel:</u></div>
<div>
<div> bnd: [1×3 struct]</div>
<div> cond: [0.3300 0.0041 0.3300]</div>
<div> mat: [3000×3000 double]</div>
<div> type: 'dipoli'</div>
<div> unit: 'mm'</div>
</div>
<div><u>electrodes:</u></div>
<div>
<div> pnt: [133×3 double]</div>
<div> label: {1×133 cell}</div>
</div>
<div><br>
</div>
<div>Code that I have used to obtained the image below:</div>
<div>
<div>ft_determine_coordsys (vol, 'interactive','no')</div>
<div><br>
</div>
<div><br>
</div>
<div>figure;</div>
<div>sens=data.elec;</div>
<div>sens=ft_convert_units(sens, 'cm');</div>
<div>ft_plot_vol(vol,'facecolor','skin','edgecolor','none')</div>
<div>ft_plot_sens(sens,'elecsize',10)</div>
<div>camlight</div>
<div>alpha 0.5 </div>
</div>
<div><br>
</div>
<div>If somebody could help my I would be very grateful,</div>
<div><br>
