Dear primers,

I have a curve that shows 4 maxima (green curve in the image, red curve is the derivative). Now i simply want the coordinates of these maxima without defining a threshold. I tried the "ExtremePoints" function, but it returns an error ("...cannot determine discontinuities") and the "extrema" function which gives me only one max and min value.It would be great, if somebody could give me a hint...
