[FieldTrip] CTF MEG current phantom

[McGowin, Inna]

Hi Andreas,
The problem is that there are no cables or connecters used for the noise
test study I did on the phantom.
Just the phantom... It seems it has some magnetic contamination and creates
a signal due to vibration.
My next step is to clean thoroughly the phantom, inside and outside, and
see will it help.
Thanks,
Inna
