The most sensible approach to take here would be to interpolate the atlas onto the low-resolution grid that was used for the sourcereconstruction+connectivity analysis, and then parcellate.
<div class="">Be aware that the functional data should be defined in the same coordinate system as the anatomical data. For the interpolation set the parameter to ‘brick0’, and the interpolation method to ‘nearest’.</div>

It occurs to me that using ft_sourceinterpolate to decrease, rather than increase, the dimensions is not intuitive, and I found that it was actually fairly easy to get the Gorden et al. atlas loaded in as they provide an MNI-registered form of the atlas. So
I repeated my steps using the selected atlas and with a smaller headmodel and leadfield resulting in a source file that had to be interpolated in the more anticipated direction. The problem persists, however.<o:p class=""></o:p></div>

As you can see, the first dimension of the cohspctrm results increased from 4050 to 271633 with interpolation and then decreased to 333, the number of parcels in my chosen atlas, exactly as I would have expected. The second dimension, however, did not budge
from its initial 4050. The interpolation step is necessary to ensure the source matches the atlas (FT throws an error otherwise).<o:p class=""></o:p></div>

My ultimate intention is actually to use the parcellation scheme proposed by Gordon et al.

The problem I ran into is that I am trying to interpolate my brain’s mesh DOWN from 15002 to 8004 (to match the atlas), not up. As you pointed out, I have had some problems with other high resolution meshes, but in this case ft_sourceinterpolate seemed to work
— it just only worked for one of the two dimensions of my connectivity data. That is, it went from<span class="Apple-converted-space"> </span><span style="" class="">a [15002×15002 double] to a [8004×15002 double]</span>. Of course it’s possible the interpolation
for that first dimension was incorrect, but what confused me was that it did not interpolate the second dimension. (As I write this, I’m wondering if I should simply try transposing the matrix and running the interpolation again!).<o:p class=""></o:p></div>

<div style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;" class="">
I will try, as you suggest, downsampling the mesh externally and trying again. I’m not able to match the 8004 vertices perfectly, but perhaps if I drop it slightly below this number it will be able to interpolate up correctly.<o:p class=""></o:p></div>

<span class="">It seems like you are using the HCP Glasser atlas ('A multi-modal parcellation of human cerebral cortex')? The atlas presented as part of the network analysis tutorial is designed for a cortical mesh with 8004 vertices, rather than the 15002
you are using. I don’t believe ft_sourceinterpolate can currently cope with the surface-based transformation upwards from 8000—> 15000 vertices. <o:p class=""></o:p></span></div>
