Electrode-Align

[Robert Oostenveld]

Dear Paul,

the first figure indeed looks quite ok. The remaining distance from the electrodes to the scalp will be removed in the BEM model setup in which the electrodes are projected on to the skin.

However, I dont understand the subsequent problem. Please file a bug at bugzilla.fcdonders.nl and attach a small *.mat file with the cfg that you give as input, i.e. such that the problem can be reproduced with 

load file.mat
elec = ft_electroderealign(cfg)
 
best,
Robert
