Dear all

I do EEG source analyse,But I use the method as the follow got strong
function connectivity from different brain areas.(eg.correlation)and
strength is similar;
I want konw  the code with source reconstruction is right?
Or some stimulate can  prove the code that is right.
(the VOL and sourcemode form template)

cfg                   = [];
cfg.covariance        = 'yes';
cfg.vartrllength      = 2;
cfg.covariancewindow  = 'all';
timelock              = ft_timelockanalysis(cfg, data);

  cfg                 = [];
 cfg.channel            = {'EEG'};
cfg.vol             = vol;
 cfg.reducerank      = 3;
 cfg.normalize  ='yes';
 cfg.elec         = data_org.hdr.elec;
cfg.grid =sourcemodel;
 [grid]= ft_prepare_leadfield(cfg);

cfg             = [];
cfg.method      = 'lcmv';
cfg.vol    = vol;
cfg.grid  = grid;
cfg.lcmv.fixedori = 'yes';
cfg.elec         = data.hdr.elec;
cfg.lcmv.keepfilter  = 'yes';
cfg.lcmv.projectnoise = 'yes';
source1         = ft_sourceanalysis(cfg, timelock);

thanks in advance
