[FieldTrip] interpolate missing grad positions

[Stephen Whitmarsh]

Hi Fan,

While Julian is of course right, and ft_channelrepair will probably do it
for you, I don't think you *have *to interpolate before doing source
modelling: just don't include those channels in your source modelling.

Someone more fluent in the underlying math can chime in, and don't take it
from me, but I would intuit that interpolating channels will make your data
rank-deficient. I doubt this would pose any real problems though.

Cheers,
Stephen
