[FieldTrip] how to make the cfg.selectfeature work in ft_databrowser?

[Diego Lozano-Soldevilla]

Hi all,

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
help me to mark different artifact trial types using the cfg.selectfeature
option? 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.

Thanks beforehand,

Diego



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
