[FieldTrip] How to obtain all trials data?

[Reo Inoue]

Dear all, Steve
I use ft_timelockanalysis before ft_sourceanalysis. I also use cfg.keeptrials='yes' there.
All the best

Hello Reo,

What was the format of the timelock data structure you supplied to
ft_sourceanalysis()? i.e., when you called ft_timelockanalysis() to create the
timelock structure earlier, did you also use cfg.keeptrials='yes' there? If not,
then your timelock structure would be an average (rather than all trials), and
thus the source data you get would also be averaged across trials.

Best,
Steve

Dear all,

I use function; ft_sourceanalysis following. [source] = ft_sourceanalysis(cfg,
timelock)
And I want to obtain the all trials data, not average. But I could not
understand why i obtain the average. My config is following. Are there any
problems?
cfg=[]; cfg.method = 'eloreta'; cfg.jackknife = 'no';%'no' or 'yes' jackknife
resampling of trials
cfg.pseudovalue = 'no';%'no' or 'yes' pseudovalue resampling of trials
cfg.bootstrap = 'no';%'no' or 'yes' bootstrap resampling of trials
cfg.numbootstrap = 1;%%number of bootstrap replications (e.g. number of
original trials) cfg.keeptrials='yes'; cfg.vol =vol; %structure with volume
conduction model, see FT_PREPARE_HEADMODEL cfg.elec =elec;%structure with
electrode positions, see FT_DATATYPE_SENS [source{SouInd,1}] =
ft_sourceanalysis(cfg, timelock);


Thanks a lot in advance,
All the best,
