Hi Cecilia,
<div class=""><br class="">
</div>
<div class="">Have you tried to compute the average on the low-resolution solutions, and only do the interpolation on the average?</div>
<div class=""><br class="">
</div>
<div class="">This should be possible, because you use the ‘mni-aligned grids’.</div>
<div class=""><br class="">
</div>
<div class="">Also, ft_sourcegrandaverage is a dinosaur of a function, and it looks as if it hasn’t grown along with the rest of the code. The pasted matlab-structure looks a bit strange, and I can imagine that FieldTrip chokes on it.</div>
<div class=""><br class="">
</div>
<div class="">Best wishes, </div>

Hi Everyone,
<div class="">I am struggling with the source analysis and especially when averaging across subjects' source reconstruction.</div>
<div class="">The analysis for every subject was done according to the tutorial (creating MNI aligned grids in individual head space).</div>
<div class="">The point is when I try to plot the source grandaverage I get an error saying there is no 'anatomy' field in my data.</div>
<div class="">I tried to use both sourceinterpolate or add the anatomy field manually to the gsource_grandaverage structure but nothing works.</div>
<div class="">Here is what my source_grandaverage contains:</div>
<div class="">ga_sources</div>
<div class=""><br class="">
</div>
<div class=""> pow: [6×902629 double]</div>
<div class=""> dim: [91 109 91]</div>
<div class=""> freq: 9.9723</div>
<div class=""> inside: [902629×1 logical]</div>
<div class=""> pos: [902629×3 double]</div>
<div class=""> unit: 'mm'</div>
<div class=""> cfg: [1×1 struct] <br class="">
<div class=""><br class="">
</div>
<div class=""><br class="">
</div>
<div class=""><br class="">
</div>
<div class="">Any help is appreciated! Thanks!</div>
