Please have a look at http://fieldtrip.fcdonders.nl/getting_started/bti.
I would not recommend the .xyz/.m4d variant, but would directly read
from the raw data files. Support for .xyz/.m4d files (these files
contain relevant header information) is implemented in fieldtrip just
for backward compatibility. These need to be created from the raw data
(using the pdf2set command (see the software manual of the MEG-system
for reference)), but contain only limited header information (e.g. the
balancing coefficients are not extracted). To me this sounds like
double work, because FieldTrip can read the header information from
the raw files directly.
