[FieldTrip] combining magnetometers and planad gradiometers for analysis

[Elena Orekhova]

Dear  fieldtrippers,
This message is mainly for Neuromag users.

When I do  'lcmv' beamforming analysis separately on planar gradiometers or magnetometers, I get quite meaningful results.
If I combine the two types of sensors without weighting, the result is meaningless.
Apparently, the algorithm does not take care of different scales and units of the GRA and MAG measurements.  Does anybody know how to deal with this problem?
