I am trying to find some documentation on the electrode number match (A1, A2 etc) in a 32 channel array. Can anyone give me a list of what goes where so I don't have to do it the hard way
Cheers
Paul

The channel numbers versus cap layout are shown here:

With the 32-channel cap, it is best to load the 10-20system32+8.cfg provided on the software CD (or on
http://www.biosemi.com/download_actiview.htm). With the 32-channel CFG loaded, the channel labels displayed in ActiView (and in the off-line review packages) will match the labels on the 32-channel cap. Consider renaming 10-20system32+8.cfg to default.cfg if the system is always used with 32-channel caps.
