[FieldTrip] Modification of ft_timelockgrandaverage cfg.keepindividual

[Lucie Charles]

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.time      = ResultsTime;       % 1 x Nsamples

%KEEP INDIVIDUAL MEANS?

else

  grandavg.var    = ResultVar;          % Nchan x Nsamples
  grandavg.dimord = 'chan_time';
