[FieldTrip] How can I use DICS to get the waveforms?

Dear all,
 I use DICS-beamformer to get the source,as follow:
cfg                   = [];
cfg.frequency         = freqP.freq;
cfg.elec              = grid.cfg.elec;
cfg.method            = 'dics';
cfg.keeptrials        = 'yes';
cfg.grid              = grid;
cfg.vol               = vol;
cfg.dics.lambda       = '5%';;
cfg.dics.realfilter   = 'yes';
source                = ft_sourceanalysis(cfg, freqP);

source =

          dim: [19 25 19]
         freq: 17.9481
    cumtapcnt: 3
          pos: [9025x3 double]
       inside: [1x4686 double]
      outside: [1x4339 double]
       method: 'average'
          avg: [1x1 struct]
          cfg: [1x1 struct]

    pow: [1x9025 double]
is it right?  if I want to get the waveforms in order to do the
correlation,how can I do ?
