[FieldTrip] from axial to planar gradiometers

Hello to everybody !
I am facing a problem with the transformation of data from axial to planar
gradiometers !
I manipulate data recorded from 248- channel BTi (4D Neuroimaging) axial
gradiometer system !
I am using cfg.planarmethod='sincos';
The basic problem is the output of ft_megplanar where labels sections have
2x248 labels (vertical & horizontal) but only 248 channels in avg section
of the struct.
I cannot understand the problem!

Can anyone have any idea ?

Best regards
Dimitriadis Stavros
