...and this might not be neccecary. Problem seems that sourceplot doesnt understand the raw sourcedata (after ft_sourcegrandaverage). Attached you'll find the raw and interpolated data, code below. % to interpolate: mri = ft_read_mri('/home/common/matlab/spm2/canonical/single_subj_T1.mnc'); cfg = []; cfg.interpmethod = 'nearest'; cfg.parameter = 'stat'; cfg.sphereradius = 0.05; intsource = ft_sourceinterpolate(cfg,rawsource,mri); % to plot: cfg = []; cfg.method = 'surface'; cfg.interactive = 'yes'; cfg.projmethod = 'nearest'; cfg.anaparameter = 'anatomy'; cfg.funparameter = 'avg.stat'; cfg.camlight = 'no'; cfg.surfdownsample = 10; cfg.colorbar = 'no'; cfg.surffile = 'surface_l4_right'; figure; ft_sourceplot(cfg, temp ); view(90,0); CAMLIGHT LEFT

I don't know what the 'temp' variable in your example code is, but when I replace it with intsource it works alright. I agree that in essence the interpolation should not be necessary and could be done on the fly, but at the moment that is just not how it works (and used to work).
