[FieldTrip] Fwd: Power Maps on Surface

[Jörn M. Horschig]

Hey.

 

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).

Best,

Hello,

 

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?

 

cfg.surffile=ft_read_headshape('cortex_5124.surf.gii');

 

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';

cfg.surffile='sourcemodel.mat';

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,

Best,

Keyvan
