hi, the help of ft_prepare_neighbours points to ft_datatype_sens for defining the structure with EEG electrode positions. ft_datatype_sens refers also to the .elecpos field The structure for EEG or ECoG channels contains sens.label = Mx1 cell-array with channel labels sens.chanpos = Mx3 matrix with channel positions sens.tra = MxN matrix to combine electrodes into channels sens.elecpos = Nx3 matrix with coil positions But if you give an elec structure with .elecpos field, for example, to ft_topoplotER, it will give an error: cfg=[]; cfg.elec; ft_topoplotER(cfg,data) where elec is elec.label elec.elecpos It works well, if elec is: elec.label elec.chanpos (or .pnt) Lilla

elec should always contain a chanpos, I guess elecpos is optional.

(In reply to comment #1) ok. can I write this then to the reference doc of ft_datatype_sens?
