Dear fieldtripers,
After running ft_definetrial and ft_preprocessing, we try to plot the
data using ft_databrowser using the script at follow:
>> cfg = [];
>> ft_databrowser(cfg, data);
But this is the error message we got:
the input is raw data with 69 channels and 25 trials
detected 0 visual artifacts
Error using zeros
Size inputs must be integers.
Error in convert_event>artifact2artvec (line 179)
artvec = zeros(length(artifact), endsample);
Error in convert_event (line 103)
obj = artifact2artvec(obj,endsample);
Error in ft_databrowser (line 501)
artdata.trial{1} = convert_event(artifact, 'boolvec', 'endsample',
datendsample); % every artifact is a "channel"
We did try to plot the raw *.cnt file (the cnt is recorded using curry
7) using ft_databrowser. It worked, but not the epoched data. This is
the parameters we used for the cfg to run ft_definetrial and
ft_preprocessing
cfg = [];
cfg.dataformat = 'ns_cnt';
cfg.headerformat= 'ns_cnt';
cfg.eventformat= 'ns_cnt';
cfg.trialdef.eventtype = 'stimtype';
cfg.trialdef.prestim = 0.5;
cfg.trialdef.poststim = 1.5;
cfg.trialdef.eventvalue = 114;
cfg.dataset = [dir filesep 'cnt' filesep subjectdata.subjectnr '_'
subjectdata.initial '_' subjectdata.date '.cnt'];
cfg = ft_definetrial(cfg);
data = ft_preprocessing(cfg);
The analysis is run on fieldtrip-20150522 and Matlab 2014a. Any help
with this will be appreciated!
Many thanks in advance,
Carmen
