Post on mailing list: Jim Parkinson <> 26 Jun (4 days ago) to fieldtrip Hi I have been using ft_singleplotTFR along with the 'outline' option to mask areas of the plot as given by an ft_freqstatistics output. I started to notice that the outline didn't match up with what (by eyeball!) should be outlined. So I checked the function by using ft_singleplotTFR cfg = []; cfg.parameter = 'mask'; = 'Cz'; cfg.zlim = [0 1]; % masks cfg.maskparameter = 'mask'; cfg.maskstyle = 'outline'; cfg.renderer = 'opengl'; ft_singleplotTFR(cfg,td); therefore I am plotting the mask data (zeros or ones) and also using that data as the outline parameter - so the outline should be EXACTLY around the RED area (ones), right? This doesn't happen (screencap here: However, the 'opacity' and 'saturation' methods work fine, and perfectly bounds the mask area. Has anyone else had this issue with 'outline', have any pointers, or alternatives that are easy to implement. p.s., I've replicated this with all rendering options, on both Mac and Linux Thanks for any help Jim

Just e-mailed Jim Parkinson: Hi Jim, Sorry for the slow reply. I tried to reproduce your report, but I am getting perfectly normal results with the following code: %% create some data freq = []; freq.label = {'a'}; freq.freq = 1:40; freq.time = 0.05:0.05:3; freq.dimord = 'chan_freq_time'; freq.powspctrm = randn(1, numel(freq.freq), numel(freq.time)); freq.mask = zeros(size(freq.powspctrm)); freq.mask(1,15:25,20:30) = 1; %% plot cfg = []; = 'a'; cfg.maskparameter = 'mask'; cfg.parameter = 'mask'; cfg.maskstyle = 'outline'; cfg.renderer = 'opengl'; ft_singleplotTFR(cfg, freq); see attached. Could you update to the latest FT version and tell me whether the problem still persists? Thanks. (By the way, it would be better to continue this discussion at our bugzilla: You can create an account there with just your e-mail address and add comments to the bug.) Best, Eelke

No reply from Jim Parkinson anymore, so marking as worksforme.
