chanpos in the grad description is all nan. This is known. Yet, when using a template neighbourhood structure, there is no reason for it not to work. Investigate the dependency of the function on the data.grad.chanpos field, and remove this if it is not necessary.

Well, a solution to make it more robust would be to supply the neighbour-template with a set of channel positions. For MEG systems at least the relative position of (and distances between) the coils is fixed

added check on chanpos being NaN. Throw instructive error if this is the case.
