I got an error when I follow the example on the wiki:[]=localspheres#local_spheres_model_from_fieldtrip_using_the_ctf_headshape hdr=ft_read_header('/data/johzum/delange2008data/dataset02.ds'); cfg=[]; cfg.grad=hdr.grad; cfg.headshape='/data/johzum/delange2008data/dataset02.shape'; ft_headshape=ft_prepare_localspheres(cfg); ft_prepare_localspheres runs fine on the 151 MEG sensors, but then crashes when it reaches channel 152 which is a reference channel. Error is: ??? Undefined function or variable "hs". Error in ==> ft_plot_mesh at 148 set(hs, 'FaceAlpha', facealpha); Error in ==> ft_prepare_localspheres at 190 ft_plot_mesh(headshape.pnt(shapesel,:), 'vertexcolor', 'g'); 'hs' doesn't exist because 'pnt' is empty. After a quick chat with JM, I have fixed this by adding to ft_plot_mesh, line 147: elseif ~isempty(pnt) && numel(facealpha)==1 It now works fine, and simply doesn't plot for channels which are outside the default radius.
