[FieldTrip] source grand average

[נועה הכהן]

!Thanks
:I tried to do this, and to used ft_sourcedescriptives but I got an error
message

Attempted to access sel(1); index out of bounds because numel(sel)=0.

Error in ft_sourceinterpolate>my_interpn (line 688)
  ft_progress(sel(1)/num, 'interpolating %.1f%%\n', 100*sel(1)/num);

Error in ft_sourceinterpolate (line 535)
    interp.inside( sel) = my_interpn(double(functional.inside), ax(sel),
ay(sel), az(sel), 'nearest', cfg.feedback);

Why?

thanks, Noa.
