Dear Stefan,

> rmbase(mydata,375,[23:37])could this be okay please?

Does your machine have to "settle" before each trial? If yes, then this 
is correct. Otherwise, simply remove the first trial and subtract 
pre-stimulus baseline (sample points [1:37] ) from other data trials.

Hope this help,

Arno
