Hello everyone,
It seems that there has been a modification of ft_timelockgrandaverage : now
if you specify cfg.keepindividual = 'yes', the grandaverage is computed but
is not included in the output of the function (see above).
Why is that ? Many of my scripts rely on this option and I wanted to know if
there was a good reason for it.
Thanks,
Lucie

grandavg = [];
grandavg.label = cfg.channel; % cell-array
%grandavg.fsample = varargin{1}.fsample; % fsample is obsolete
grandavg.time = ResultsTime; % 1 x Nsamples
%KEEP INDIVIDUAL MEANS?
if strcmp(cfg.keepindividual, 'yes')
* grandavg.individual = avgmat; % Nsubj x Nchan x Nsamples
grandavg.dimord = 'subj_chan_time';*
else
* grandavg.avg = ResultGrandavg; % Nchan x Nsamples*
grandavg.var = ResultVar; % Nchan x Nsamples
grandavg.dimord = 'chan_time';
end
