Hello When running the ft_topoplotIC(cfg,comp) it get Error using ft_checkdata (line 525) This function requires 'raw+comp' or 'raw' data as input, see ft_datatype_raw. Error in ft_preprocessing (line 281) data = ft_checkdata(data, 'datatype', {'raw+comp', 'raw'}, 'hassampleinfo', 'yes'); Error in topoplot_common (line 395) data = ft_preprocessing(cfg.preproc, data); Error in ft_topoplotIC (line 171) [cfg] = topoplot_common(cfg, comp); eventhough the comp has a sampleinfo field. I tried it with different version and on Mac, Windows and Linux, but to no avail. It ran on my colleagues Mac using 20180810 Fieldtrip.

please provide us with some data and a snippet of code to reproduce your problem.

Thank you. I will provide a Google Drive link to the data, that includes the cfg, the data and the comp structure: https://drive.google.com/open?id=1m97dqOfEEC9GbAfq8DFaI7chijX33YPO

sending ~1GB of data is a bit unpractical. In the future, please prune the data such that it is as small as possible in volume, but still in a shape to reproduce your problem.

I cannot reproduce the problem. Please upload the cfg you use for plotting, and a new data file, with only 10 trials or so: cfg = []; cfg.trials = 1:10; data = ft_selectdata(cfg, data); comp = ft_selectdata(cfg, comp);

I guessed some layout, and ran into an error that relates to complex-values in the mixing matrix. This latter issue is a user error, which you get when rank-deficient data is subjected to an ICA (this happens for instance when the data are re-referenced to an average reference).
