<div style="direction: ltr;font-family: Tahoma;color: #000000;font-size: 10pt;">Hi All,
<div><br>
</div>
<div>I have a question regarding dipole fitting and aligning anatomical images and volume conduction models with MEG sensors.</div>
<div>I know a lot of other people have posted on related issues on this email list, but looking through previous emails, I can't see the solution to my current problems.</div>
<div>Any help, much appreciated.</div>
<div><br>
</div>
<div>Ultimately, when I use <span style="font-family: Courier; font-size: 10px;">ft_dipolefitting </span><span style="font-size: 10pt;">and plot with </span><span style="font-family: Courier; font-size: 10px;">ft_sourceplot</span>,<span style="font-family: Courier; font-size: 10px;"> </span><span style="font-size: 10pt;">I
end up with 'dipoles' appearing outside the head......</span></div>
<div><span style="font-size: 10pt;"><br>
</span></div>
<div><font size="2">Checking the registration of my volume conduction model with sensors, it also appears the volume conduction model is aligned </font>unrealistically<font size="2"> high within the sensors (see jpg).</font></div>
<div><font size="2"><br>
</font></div>
<div><font size="2">Yes, I have checked that the coordsys and units are the same for sensors, mri, segmented mri and volume conduction model. I am using a neuromag system, and use </font><span style="font-family: Courier; font-size: 10px;">ft_volumerealign </span><span style="font-size: small;">with
</span><span style="font-family: Courier; font-size: 10px;">cfg.method = </span>
<span style="font-family: Courier; font-size: 10px; color: rgb(178, 69, 243);">'interactive' </span><span style="font-size: small;">and </span><span style="font-family: Courier; font-size: 10px;">cfg.coordsys = </span><span style="font-family: Courier; font-size: 10px; color: rgb(178, 69, 243);">'neuromag' </span><span style="font-size: small;">to
bring the MRI into neuromag coordinates.</span></div>
<div><span style="font-size: small;"><br>
</span></div>
<div><font size="2">I can't see where co-registration problems are arising, or why the dipoles should be being shown as appearing outside the head.</font></div>
<div><font size="2"><br>
</font></div>
<div><font size="2">I have fussed over this for so long, if anyone can point me towards the light I will be utterly grateful.....</font></div>
