Could you email (cut past from matlab) any of the warnings and errors
that the call to MULTIPLOTER produced, thanks.

It is also possible that this strange behaviour of MULTIPLOTER may
have something to do with some minor changes that were recently made
to the layout structure used by FT. There is now a function called
PREPARE_LAYOUT (download the latest version of FT, and it lives in
the fieldtrip directory) which will generate the correct layout
structure for you, using the gradiometer information in your data
structure. Try using the layout generated by this function for
plotting, and please let me know if there are any errors.
