I'm using ft_databrowser to inspect sleep data and I want to visually mark different events (spindles, k-complexes, artifacts, so forth) and asign them to different cfg.artfctdef.xxx.artifact substructures. Could somebody give a hint me to mark different artifact trial types using the cfg.selectfeature option? It's not obvious to me where to start the fix. Please find below the code and data to reproduce the error I got. I'm using the very last fieldtrip version on windows with matlab 7.9b. data = []; data.label = {'Fpz';'F7';'F3';'Fz';'F4';'F8';'C3';'Cz';'C4';'P3';'Pz';'P4';'O1';'Oz';'O2'}; data.fsample = 250; data.trial{1} = rand(size(data.label,1),data.fsample*30); data.time{1} = (1:data.fsample*30)./data.fsample; cfg = []; cfg.length = 2; cfg.overlap = 0; trl = ft_redefinetrial(cfg,data); cfg = []; cfg.channel = 'all'; cfg.blocksize = 2; cfg.selectfeature = {'a';'b'}; cfg.viewmode = 'vertical'; events = ft_databrowser(cfg,trl); the input is raw data with 15 channels and 15 trials detected 0 a artifacts detected 0 b artifacts ??? Error using ==> plus Matrix dimensions must agree. Error in ==> ft_databrowser at 745 hsel = [1 2 3] + (opt.ftsel-1) .*3; ??? Reference to non-existent field 'trlvis'. Error in ==> ft_databrowser>redraw_cb at 1639 begsample = opt.trlvis(opt.trlop, 1); Error in ==> ft_databrowser>winresize_cb at 2250 redraw_cb(h,eventdata); ???

I added a condition check to prevent the crash, @Roemer please review. this pertains to PR597 on github
