[FieldTrip] question about source reconstruction with eloreta

[Pierpaolo Croce]

Dear Fieldtrip experts,
I'm trying to reconstruct an EEG-ERP with eloreta method
I'm using the following code:

cfg               = [];
cfg.method        =  'eloreta' ;
cfg.grad = elec_new;
cfg.grid          = leadfield;
cfg.headmodel     = vol;
cfg.eloreta.lambda = 0.05;
GA_2.label = elec_new.label;
sGA_2 = ft_sourceanalysis(cfg,GA_2);

where GA_2 is:
GA_2 =
  struct with fields:
       avg: [122×1751 double]
       var: [122×1751 double]
       dof: [122×1751 double]
      time: [1×1751 double]
     label: {122×1 cell}
    dimord: 'chan_time'
       cfg: [1×1 struct]

I expected to obtain (as happens using 'mne' method) a .pow matrix with
dimensions nVoxels x nTimeFrames.
On the contrary, I obtained a .pow matrix with dimension nVoxels x 1.
Am I missing something?
Can someone help me to understand where I'm wrong?
Thanks in advance.
Pierpaolo
