Hi.

No, I don't know anything.  You might ask on the Neuromonitoring List;
someone might know something.
Cadwell, and perhaps some other manufacturers, have automatic peak
picking on their equipment, but they don't sell the software
separately, and if they did I'm sure it would cost more than that.  And
even then, the peak picking software makes errors, especially on the
first trial, so you have to supervise it.  There might be some program
you could get, but it probably would either
1) be incompatible with your collection software, or
2) require human supervision.
I'd suggest training whoever collects the data to pick the peaks then
and there.

Good luck.

Jerry
