Hi Anas,
<div><br>
</div>
<div>Why don’t you just use ft_sourceplot for visualization of the volumetric atlas? Many unexpected things might happen if you use some (ad hoc) way to mapping the segmentation onto a poorly defined mesh.</div>
<div><br>
</div>
<div>something like this should do the trick:</div>
<div><br>
</div>
<div>atlas.tissue = double(atlas.tissue);</div>
<div><br>
</div>
<div>cfg = [];</div>
<div>cfg.funparameter = ’tissue’;</div>
<div>ft_sourceplot(cfg, atlas);</div>
<div><br>
</div>
<div>Best wishes,</div>
<div>Jan-Mathijs</div>

<br>
I am attempting to visualize the cortical parcellation based on the Yeo7 network atlas provided by freesurfer. My end goal is to localize some intracranial EEG electrodes, but I wanted to confirm the labeling is reasonable first. I am using the ft_volumelookup
and ft_plot_mesh functions to do this. I noticed some striking issues: gross hemispheric asymmetries, absent networks, large portions of the cortex not labeled/plotted. Based on my research, it is my understanding that ft_volumelookup is not actively maintained.
Is there a more appropriate function/cfg I should be using for this purpose? I have attached screenshots of both hemispheres and my code which should be runnable after just changing the fieldtrip path and will produce the same figure. Thanks for your time!<br>
