sourcestatistics question

[Floris de Lange]

Dear FieldTrippers,

I have a question concerning sourcestatistics.
I have calculated the source localization using DICS for 11 individual
subjects. Now I would like to test for the significance of the sources
using sourcestatistics. The examples I find in the tutorial are about
checking for significance within one subject by shuffling the individual
trials. However, what I would like to do is to do the statistics on the
2nd level (subject), and to test for the consistency of the source
reconstructions across subjects.
Is this possible with sourcestatistics? If so, how should I feed the
data to sourcestatistics? If I say something like stats =
sourcestatistics(cfg,sources{1:11}) where each source{} is a normalized
source (calculated by sourceanalysis, normalized with
sourceinterpolate), it complains (rightfully) that there's a reference
to the non-existing field 'statistic'.

Any ideas are greatly appreciated!

Kind regards,
Floris
