it should have a slider to scroll through time and allow the brain to be rotated in 3d

svn revision 2916 contains an initial implementation of the MNE source reconstruction movie. It is called ft_sourcemovie. Please give me suggestions and feedback on how to improve the visualisation.

also add a slider to movieplotER

also for TFR?

I have followed Robert's instruction to use the ft_sourcemovie function: > source5.pnt = sourcespace3.pnt; > source5.tri = sourcespace3.tri; > source5.avg.ampl = sqrt(source5.avg.pow); > > > cfg = []; > cfg.zparam = 'avg.pow'; %or 'avg.ampl' or not specified > ft_sourcemovie(cfg, source5) And I got an error: ???Error using ==> ft_plot_mesh Too many output arguments. Error in ==> ft_sourcemovie at 129 hs=ft_plot_mesh(hs, 'edgecolor', 'none', 'vertexcolor', 0*opt.dat(:,1)); source5 and sourcespace3 are in /home/language/lilmag/NCLAssis/FieldTripAnalysis/tutorial

Please give me suggestions > and feedback on how to improve the visualisation. My remarks and suggestions: 1. The time = ... at the bottom of the picture is not working at all And it is covered by the brain when I see the brain from above. 2. There is a strange thing: If I put the colorbar on the side of the picture, it seems that the values that are assigned to certain colors are changing. You can see that on /home/language/lilmag/NCLAssis/FieldTripAnalysis/tutorial/sourcemovie1.jpg and at sourcemovie2.jpg. They are pictures from the same movie at different points in time, you can see that the colorbars are different. 3. I am wondering if it would be useful to be able to specify a time-window from which the movie should be made. 4. (How) is it possible to save the movie? Lilla

Hi Lilla, I just made some changes to ft_sourcemovie, fixing the colorbar/colorscale issue. Moreover, you can now specify a mask, e.g. cfg.mask = 'mask'; source.mask = double(source.avg.pow > 1e-8); if you then start the movie, it becomes even more attractive to look at ;o)
