The variable names you are using appear to suggest that you are applying a nonlinear warp to a set of coordinate triples - the resulting coordinates are unlikely to ever be regularly spaced. If you need the output to be regularly spaced like a volume file, you need to do a resampling, not a transform of the coordinates.
I haven't worked with the MEG data or pipelines, though, so someone else will need to help you.
