[FieldTrip] empty vertices in surface sourceplot

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

Dear Tzvetan,

There are some options in ft_sourceplot (relating to the surface plotting) that can be tweaked in order to influence the interpolation onto the template surface. I don’t know them by heart, but they should be recoverable from the help section of the function.

Best wishes,
JM

Dear all,

I am working with a source map (panel A in the attached figure) reconstructed in the Yeo17 atlas space. The result of ft_sourceparcelate (panel B) looks reasonable to me. I would like to plot this on the cortical surface. Yet I also get some empty patches (panel C). Has anyone run into the same problem and figured out a solution?

This is my configuration during the surface plot:
cfg = [];
cfg.method         = 'surface';
cfg.funparameter   = 'pow';
cfg.surffile       = 'surface_white_both.mat';
cfg.surfinflated       = 'surface_inflated_both.mat';
cfg.camlight       = 'no';
ft_sourceplot(cfg, parcel);
view ([0 0])
light('Position',[0 -1 0]);


Thanks a bunch!
tzvetan
