Re: Electrode proximity/distance

Hmm, not sure if this is a *good* solution, but once I thought of it the rest was easy so here it is: function [epmap rownm colnm] = electrodeProximity( EEG ) %% Calculates the Euclidean distances between all pairs of electrodes given % % Note: The function disregards "non-EEG" channels. These are t...

Re: Electrode proximity/distance

Addendum: of course I would also be happy to see a method for calculating the proximity table myself based on spherical or XYZ coordinates.

Electrode proximity/distance

Hello, is there a handy index available to read out the distances between electrodes in the Biosemi caps? For instance, I have data from the Biosemi 128 cap, with A1-32, B1-32, C1-32, D1-32 electrodes. If I want to define a region of interest in Matlab, I must select specific sets of electrodes beca...
