Narayan and Arjen already pointed you in the appropriate direction. Just to clarify their emails, FieldTrip uses a layout structure for 2-D plotting of data, and the electrode structure for a 3-D representation. The electrode structure can be converted to a 2-D layout, but can also be used for source reconstruction, for which the layout is useless.
and pointers to other documentation therein.
