locations using neighbourdist values between 1 and 100, and then evaluated each
structure to see which one specified 5 neighbors for T8, 8 for Cz, and 4 for
Fp1. 48, 49, and 50 seemed to satisfy this so I just took the middle value.<o:p></o:p></span></p>

<p class=MsoNormal><span lang=EN-GB>Please can someone tell me whether the
cfg.neighbourdist needed to define clusters is in cm or mm? (i.e. if I

in which your sensor coordinates (in the .grad or .elec field) are expressed.
