Problems with plotting sourcestatistics (partially) solved

[Michael Wibral]

Dear Fieldtrippers,

a while ago I posted to this list about some problems with plotting
sourcestatistics for multiple subjects. That problem is solved by now,
fortunately - the plotting routine after sourcestatistics simply needed an
additional cfg.sourceunits='mm' although I do not get exactly where this
information got lost on the way. The other problem I have now is that,
despite (nonlinear) volume-normalisation the brains of my subjects do not
seem to share too many voxels, i.e. the ".inside" field of sourcegrandaverage
is pretty small. Even if I fake perfectly matching subjects by feeding the
same subject 10 times the area used for the statistics is considerably
smaller than the brain in the template MRI.
Any idea what could be wrong? I made grid and hdm for the individual
subjects as described in the tutorial and used Guido Noltes hdm - is that
too spherical, possibly?? my result are especially "brain deficient" at the
occipital pole.

Thanks for your help,
Michael Wibral
