Hi Paolo,
<div class=""><br class="">
</div>
<div class="">No it isn’t. The idea behind the cortical surface reconstruction scheme - as advertised among others in the tutorial you refer to - is that the meshes are created according to the recipe from a given template, with a specific number of vertices.
The recipe results in meshes that are topologically equivalent to each other, in which a given vertex in mesh A can be directly compared with the same (ordinal) vertex in mesh B. The atlas you refer to, and which I assume you found on
<a href="https://data.donders.ru.nl/collections/di/dccn/DSC_3011020.09_410?4" class="">
https://data.donders.ru.nl/collections/di/dccn/DSC_3011020.09_410?4</a> is based on a cortical sheet that contains 8196 vertices. It has been created using an older version of the recipe in the tutorial, back in the days that we used the MNE-software (the compiled
C-based code, rather than MNE-python) for the ‘downsampling’ of the Freesurfer generated meshes, followed by a Caret-based script for the surface registration.</div>
<div class=""><br class="">
</div>
<div class="">I don’t think that it makes much sense to try and interpolate the different topologies on each other. So, there are 2 potential solutions here.</div>
<div class="">1) you generate your surface meshes using the old recipe, resulting in 8196-vertex meshes for your subjects.</div>
<div class="">2) you generate a low-resolution version of the Conte69 atlas using HCP-workbench, using the same spherical template meshes (mapping the 164k per hemisphere to the 8k per hemisphere meshes), and apply a ’subparcellation’ scheme to chop up the
large Brodmann areas in smaller chunks.</div>

Is there a cortical atlas available to interpolate with the sourcemodel mesh described here?<br class="">

I found the atlas_conte69_8196reg_LR_brodmann_subparc.mat atlas in the donders repository. Is this the most appropriate atlas to interpolate my sourcem<span class="gmail_default" style=""><font size="4" class=""></font>e<font size="4" class=""></font></span>sh
