[FieldTrip] again on plv

Hi Fieldtrippers,
I thought I had quite a simple task but it's coming more and more an hassle
(at least for me) so I'm here asking from your knowledge.

I would like to find the plv.

As far as I've seen now the plv is inside the ft_connectivityanalysis and is
taking freq data as input.

ok, so I did:

cfg = [];
cfg.method     = 'wavelet';
cfg.output     = 'powandcsd';
cfg.foi        = 1:1:44;
cfg.toi        = -0.999:0.01:1;
cfg.keeptrials = 'yes';
WG = ft_freqanalysis(cfg, dataG);

Now my question is how to optimize the width and the gwidth.
The point is that I don't know yet in which freq to search so I have quite a
big foi 1:44 and not such a good shape is performed.

I've tried tfr but no csd is given so no plv.

I have to use any other multitapers?

Sorry for this trivial question.

Marco
