hi jim ,
good work !
why didn't you tell us you were a brain researcher ?
i thought you were just an engineer ,like the rest of us here :)
does your code works in real time ?
could it , by simple means , become used for training ?
and did you post something about this to the biofbp / biofeedback
yahoo groups ? there could be an interesting discussion there about
this subject .
sincerly
yaniv
