[FieldTrip] Yeo7 Atlas Cortical Parcellation

[Schoffelen, J.M. (Jan Mathijs)]

Hi Anas,

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.

something like this should do the trick:

atlas.tissue = double(atlas.tissue);

cfg = [];
cfg.funparameter = ’tissue’;
ft_sourceplot(cfg, atlas);

Best wishes,
Jan-Mathijs

Hello,

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!
