I am working on testing source-analysis with minimum-norm estimate in
FieldTrip. I would like to compare the results with MNE Suite. For the
comparison, I am using a phantom (MEG) dataset, and I would like to use
a spherical volume conductor model (r=10 cm, origin at [0 0 0],
conductivity = 1) and a surface at [0 0 7] with .5 (cm) spacing.
I am wondering if I could get any help to create this spherical volume
conductor and the simple surface that it is in the appropriate format
for MNE Suite.
Maybe someone will be interested later in the answer for my question.
I have realized that it is possible to create a volumetric or discrete
source space of arbitrary located source points, and to create bem
meshes from ascii files with the mne_volume_source_space and
mne_surf2bem utilities. They are described in the tutorial. Sorry for
the unnecessary posting.

Hi Lilla,
Also, note that you can readily use the spherically symmetric
conductor model in the forward calculation by using
mne_forward_solution directly rather than the mne_do_forward_solution
wrapper script.
Unfortunately, there are no volume data visualization tools in MNE.
You need to use the FreeSurfer tools for this.
