[FieldTrip] Fwd: Power Maps on Surface

You should specify cfg.surffile really as the path to the file, and not read in the content apriori. This section here might help (the ‘exercise’ part of the tutorial lists a cfg-example for surface plotting).

Your code is right I also encouter the same problem but you can project on the surface with ft_plot_mesh

ft_plot_mesh(bnd, 'vertexcolor', m);
bnd is the your source modle and m is avg.pow value

Dear Fieldtrip Users,



I used the surface file "cortex_5124.surf.gii" to restrict sources on cortex. I wonder how I can plot powermaps on surface?




even I save it's output in a new .mat file: "sourcemodel.mat" and tried 

cgf.surffile =  'sourcemodel.mat';


in either case the function "ft_sourceplot"  gives error.


cfg = [];

cfg.method         = 'surface';

cfg.funparameter   = 'avg.pow';

cfg.funcolormap    = 'jet';


ft_sourceplot(cfg, src)


In my code I have defined surface vertices and triangles, as well as power per vertex, I wonder What is wrong in my code? 


Many Thanks in advance,
