[FieldTrip] Source reconstructions

[Elene Beitia Loinaz]

Thank you Diego,

I already know that. But if I put it in 'mm' it is even smaller, that is
way I put in 'cm'.

As I have writen above the structure of the electrodes does not have units,
I think that the problem is there.

*electrodes:*
      pnt: [133×3 double]
      label: {1×133 cell}

If someone could help me to obtain the same size for the electrodes and for
the headmodel I would be very grateful,

Elene.
